Editor should consider publishing correction if minor errors that do not effect the results, interpretations and conclusions of the published paper are detected. Editor should consider retraction if major errors and/or misconduction that invalidate results and conclusions are detected.

Editor should consider issuing an expression of concern if there is evidence of research or publication misconduct by the authors; there is evidence that the findings are not reliable and institutions of the authors do not investigate the case or the possible investigation seems to be unfair or nonconclusive.

The guidelines of COPE and ICJME are taken into consideration regarding correction, retractions or expression of concern.

Retraction

Journal follows COPE’s Retraction Guidelines in case of retraction.

The editor has the right to retract an article if:

• There is clear evidence that the findings are unreliable; either as a result of a major error (e.g. miscalculation or experimental error), or as a result of fabrication (e.g. of data) or falsification (e.g. image manipulation).
• It contains plagiarised content.
• It has been published elsewhere without proper attribution.
• It contains material or data without authorisation for use.
• There is copyright infringement or there is some other serious legal issue.
• It reports unethical research.
• There is evidence that the peer-review process is compromised or manipulated.
• The author(s) failed to disclose a significant competing interest (also known as a conflict of interest) that, in the opinion of the editor, would have unduly influenced the interpretation of the work or the recommendations of the editors and peer reviewers.

In case of retraction the following steps are followed:

• Retraction notice including article title is published in a subsequent issue of the journal. The retraction notice is paginated and listed in the table of contents.
• A link is provided between the retraction notice and the original article in the electronic version.
• The online article is preceded by a page containing the retraction notice; the reader can then proceed to the article itself.
• The original article remains unchanged, except for a watermark on the .pdf on each page stating that it has been "retracted”.

Article Removal for Legal Reasons

In the following circumstances, except the metadata (title and authors), the text of the article is removed and a page informing that the article has been removed for legal reasons replaces the article.

• The article is found to be defamatory or to infringe the legal rights of others, and retraction is not deemed to be an adequate solution.
• The article has been, or is reasonably likely to be the subject of a court order.
• There is a significant risk to public health.

The Journal takes as principle to comply with the ethical standards of World Medical Association (WMA) Declaration of Helsinki – Ethical Principles for Medical Research Involving Human Subjects and WMA Statement on Animal Use in Biomedical Research.

An approval of research protocols by the Ethics Committee in accordance with international standards mentioned above is required for experimental, clinical, and drug studies and for some case reports. If required, ethics committee reports or an equivalent official document will be requested from the authors. For manuscripts concerning experimental research on humans, a statement should be included that shows that written informed consent of patients and volunteers was obtained following a detailed explanation of the procedures that they may undergo. For studies carried out on animals, the measures taken to prevent pain and suffering of the animals should be stated clearly. Information on patient consent, the name of the ethics committee, and the ethics committee approval number should also be stated in the Materials and Methods section of the manuscript. It is the authors’ responsibility to carefully protect the patients’ anonymity. For photographs that may reveal the identity of the patients, signed releases of the patient or of their legal representative should be enclosed.

The journal requires the authors and all individuals taking part in the evaluation process to disclose any existing or potential conflict of interest (such as financial ties, academic commitments, personal relationships, institutional affiliations) that could unduly influence one’s responsibilities.  To disclose potential conflicts of interest, the ICMJE Potential Conflict of Interest Disclosure Form should be filled in and submitted by authors as explained in the Author Form of the journal. Cases of a potential conflict of interest are resolved  within the scope of COPE Conflict of Interest Flowcharts and ICMJE Conflict of Interest guidelines

Original Articles: This is the most important type of article since it provides new information based on original research. The main text of original articles should be structured with Introduction, Material and Method, Results, Discussion, and Conclusion subheadings. Please check Table 1 for the limitations for Original Articles.

Statistical analysis to support conclusions is usually necessary. Statistical analyses must be conducted in accordance with international statistical reporting standards (Altman DG, Gore SM, Gardner MJ, Pocock SJ. Statistical guidelines for contributors to medical journals. Br Med J 1983: 7; 1489-93). Information on statistical analyses should be provided with a separate subheading under the Materials and Methods section and the statistical software that was used during the process must be specified.

Units should be prepared in accordance with the International System of Units (SI).

Editorial Comments: Editorial comments aim to provide a brief critical commentary by reviewers with expertise or with high reputation in the topic of the research article published in the journal. Authors are selected and invited by the journal to provide such comments. Abstract, Keywords, and Tables, Figures, Images, and other media are not included.

Invited Review Articles: Reviews prepared by authors who have extensive knowledge on a particular field and whose scientific background has been translated into a high volume of publications with a high citation potential are welcomed. These authors may even be invited by the journal. Reviews should describe, discuss, and evaluate the current level of knowledge of a topic in clinical practice and should guide future studies. The main text should contain Introduction, Clinical and Research Consequences, and Conclusion sections. Please check Table 1 for the limitations for Review Articles.

Case Reports: There is limited space for case reports in the journal and reports on rare cases or conditions that constitute challenges in diagnosis and treatment, those offering new therapies or revealing knowledge not included in the literature, and interesting and educative case reports are accepted for publication. The text should include Introduction, Case Presentation, Discussion, and Conclusion subheadings. Please check Table 1 for the limitations for Case Reports.

Letters to the Editor: This type of manuscript discusses important parts, overlooked aspects, or lacking parts of a previously published article. Articles on subjects within the scope of the journal that might attract the readers’ attention, particularly educative cases, may also be submitted in the form of a “Letter to the Editor.” Readers can also present their comments on the published manuscripts in the form of a “Letter to the Editor.” Abstract, Keywords, and Tables, Figures, Images, and other media should not be included. The text should be unstructured. The manuscript that is being commented on must be properly cited within this manuscript.

Table 1. Limitations for each manuscript type

Tables should be included in the main document, presented after the reference list, and they should be numbered consecutively in the order they are referred to within the main text. A descriptive title must be placed above the tables. Abbreviations used in the tables should be defined below the tables by footnotes (even if they are defined within the main text). Tables should be created using the “insert table” command of the word processing software and they should be arranged clearly to provide easy reading. Data presented in the tables should not be a repetition of the data presented within the main text but should be supporting the main text.

Figures, graphics, and photographs should be submitted as separate files (in TIFF or JPEG format) through the submission system. The files should not be embedded in a Word document or the main document. When there are figure subunits, the subunits should not be merged to form a single image. Each subunit should be submitted separately through the submission system. Images should not be labeled (a, b, c, etc.) to indicate figure subunits. Thick and thin arrows, arrowheads, stars, asterisks, and similar marks can be used on the images to support figure legends. Like the rest of the submission, the figures too should be blind. Any information within the images that may indicate an individual or institution should be blinded. The minimum resolution of each submitted figure should be 300 DPI. To prevent delays in the evaluation process, all submitted figures should be clear in resolution and large in size (minimum dimensions: 100 × 100 mm). Figure legends should be listed at the end of the main document.

All acronyms and abbreviations used in the manuscript should be defined at first use, both in the abstract and in the main text. The abbreviation should be provided in parentheses following the definition.

When a drug, product, hardware, or software program is mentioned within the main text, product information, including the name of the product, the producer of the product, and city and the country of the company (including the state if in USA), should be provided in parentheses in the following format: “Discovery St PET/CT scanner (General Electric, Milwaukee, WI, USA)”

All references, tables, and figures should be referred to within the main text, and they should be numbered consecutively in the order they are referred to within the main text.

Limitations, drawbacks, and the shortcomings of original articles should be mentioned in the Discussion section before the conclusion paragraph.

When submitting a revised version of a paper, the author must submit a detailed “Response to the reviewers” that states point by point how each issue raised by the reviewers has been covered and where it can be found (each reviewer’s comment, followed by the author’s reply and line numbers where the changes have been made) as well as an annotated copy of the main document. Revised manuscripts must be submitted within 30 days from the date of the decision letter. If the revised version of the manuscript is not submitted within the allocated time, the revision option may be canceled. If the submitting author(s) believe that additional time is required, they should request this extension before the initial 30-day period is over.

Accepted manuscripts are copy-edited for grammar, punctuation, and format. Once the publication process of a manuscript is completed, it is published online on the journal’s webpage as an ahead-of-print publication before it is included in its scheduled issue. A PDF proof of the accepted manuscript is sent to the corresponding author and their publication approval is requested within 2 days of their receipt of the proof.

The type of research ( case report, descriptive, cross sectional ,cohort, case-control, intervention, clinical trials, methodologic) must be written in the article to be sent.

For the samples included in the study, the sample size should be indicated. (Type I, Type II error and power)

Reporting of Design and Statistical Analysis

Follow existing reporting guidelines for the type of study you are reporting, such as CONSORT for randomized trials, ReMARK for marker studies, TRIPOD for prediction models, STROBE for observational studies or AMSTAR for systematic reviews.

If study cohort, fully describe cohort selection.

Describe the practical steps of randomization in randomized trials.

Descriptive statistics should be given according to the characteristics of the measurement level.

Do not treat categorical variables as continuous.

Avoid categorization of continuous variables unless there is a convincing rationale.

The methods used in statistical analysis (parametric and nonparametric tests ) should be explained in detail.

Statistical methods should describe the study questions and statistical approaches used to address each question.

Statistical methods should be described in sufficient detail to allow replication by an independent statistician given the same data set.

Take care interpreting results when reporting multiple p-values.

When reporting p-values be clear about the hypothesis tested and ensure that the hypothesis is sensible.
