  6. Clinical studies. Randomised controlled trials (RCTs), cohort and case-control studies are welcome. Materials and methods and clinical procedures have to be described in detail. Ample space will be given to high-quality colour illustrations, radiographs and drawings describing the clinical procedures used, to allow readers better understanding. Manuscripts should be
    submitted according to the following transparent guidelines:
    • randomised controlled trials (CONSORT: http://www.consort-statement.org/),
    • observational studies: epidemiology (http://www.strobe-statement.org/),
    • diagnostic accuracy studies (STARD: http:// www.stard-statement.org);
  7. Case reports presenting rare complications, conditions or specially interesting findings or procedures may be exceptionally accepted at full discretion of the editor; however, higher levels of evidence are encouraged where possible. In vitro and animal studies are not within the scope of CTD.


MANUSCRIPT PREPARATION

The components of a manuscript should consist of: title page, conflict of interest Notification page, keywords, structured abstract, body of text, acknowledgements, references, illustrations (including legends) and tables. Manuscripts must be original and written in UK English.

Title page. The first page should include:

  1. The title of the article (descriptive but concise, including the study design).
  2. The full names and professional/academic affiliations of all authors. All authors must have made substantive intellectual contribution to the study. For authorship of multi-centre trials, the individuals directly responsible for the manuscript should be identified. Multiple first authors are not allowed.
  3. Contact details including email address should be provided for the corresponding author.
  4. If the paper was presented at a meeting, the name of the organisation, location and date of the meeting should be included.
  5. Running head of no more than 50 characters (including spaces).
  6. A portrait photograph of the first author.
  7. Conflicts of interest notification. A statement of financial or other relationships that might lead to a conflict of interest including mentioning of free materials donated by companies whose products are tested in the trial. In the case of false statement CTD has the right to retract the
    published article(s) and not accept any more manuscripts from the same person.
  8. Keywords. Present 3 to 5 keywords or short phrases that capture the main topics of the article. Terms from the Medical Subject Headings (MeSH) list of Index Medicus should be used (www.nlm.nih.gov/mesh); if suitable MeSH terms are not yet available for recently introduced terms, other terms may be used.

Abstract. A structured abstract: purpose, materials and methods, results, conclusions,is mandatory.

Introduction. Provide a context or background for the study (i.e. the nature of the problem and its significance). State the specific purpose or research objective of, or hypothesis tested by, the study or observation; the research objective is often more sharply focused when stated as a question. Both the main and secondary objectives should be made clear, and any pre-specified subgroup analyses should be described. Give only strictly pertinent references and do not include data or conclusions from the work being reported.

Materials and methods. Include only information that was available at the time the plan or protocol for the study was written. All information obtained during the conduct of the study belongs in the Results section. Describe your selection of observational or experimental participants (patients, including controls) clearly, including eligibility and exclusion criteria and a description of the source population. Identify the methods, apparatus (give the manufacturer’s name, town and country in parentheses), and procedures in sufficient detail to allow other researchers to reproduce the results. Give references to established methods, including statistical methods (see below); provide references and brief descriptions for methods that have been published but are not well known; describe new or substantially modified methods, give reasons for using them, and evaluate their limitations. Identify precisely all drugs and chemicals used, including generic name(s), dose(s), and route(s) of administration. Describe statistical methods with enough detail to enable a knowledgeable reader with access to the original data to verify the reported results. Analyse the patient as the unit of statistical analysis or take into account the structure of data, for example implants clustered within patients. When possible, quantify findings and present them with appropriate indicators of measurement error or uncertainty (such as confidence intervals). Avoid relying solely on statistical hypothesis testing, such as the use of P values, which fails to convey important information about effect size. References for the design of the study and statistical methods should be to standard works when possible (with pages stated). Define statistical terms, abbreviations, and most symbols. Specify the computer software used. Authors submitting review manuscripts should include a section describing the methods used for locating, selecting, extracting, and synthesising data. These methods should also be summarised in the abstract.

Results. Present your results in logical sequence in the text, tables and illustrations, giving the most important findings first. Do not repeat in the text all the data in the tables or illustrations. When data are summarised give absolute numbers from which percentages can be calculated, and specify the statistical methods used to analyse them. Restrict tables and figures to those needed to explain the argument of the paper and to assess its support. Use graphs as an alternative to tables with many entries; do not duplicate data in graphs and tables. Guidelines for reporting statistics results can be found in Lang TA, Secic M. How To Report Statistics in Medicine. Annotated Guidelines for Authors, Editors, and Reviewers. 2nd Edition, Philadelphia: American College of Physicians 2006.

Discussion. Emphasise the new and important aspects of the study and the conclusions that follow from them. Do not repeat in detail data or other material given in the Introduction or the Results section. State the limitations of the work being reported, compare your results with other similar relevant studies, and explore the implications of the findings for future research and for clinical practice. State new hypotheses when warranted, but clearly label them as such. Describe in details the limitations of the study and discuss about the possible generalisation of the results.

Conclusions. Link your conclusions with the goals of the study but avoid unqualified statements not adequately supported by the data. State the clinical implications of your findings.

Acknowledgements. Individuals who have made substantive contributions to the study should be acknowledged. Specify any grants or other financial support. If data (i.e. individual patient data) related to a manuscript are not presented in the manuscript but are available from the author or other source, or are online, information on how to obtain this material may be given in the Acknowledgements section.

Abbreviations. Use only standard abbreviations. Avoid abbreviations in the title. The full term for an abbreviation should precede its first use in the text unless it is a standard unit of measurement.

Trade names. Generic terms are to be used whenever possible, but trade names and manufacturers should be included in parentheses when first mentioned.

Units of measurement. The International System of Units (SI) should be used. Measurements of length, height, weight and volume should be reported in metric units (metre, kilogram or litre) or their decimal multiples. Temperatures should be in degrees Celsius. Blood pressures should be in millimetres of mercury.

References. Readers should be provided with direct references to key original research sources, whenever possible. All references must be cited in the text, using the Vancouver (numbered references) style. Please refer specifically to reliable studies which are properly addressing the matter under discussion. Be balanced and mention also reliable studies which present results different from your findings/views. References should be marked in order of appearance with superscript numbers, and listed numerically in the reference list at the end of the article.

Avoid citing a “personal communication” unless it provides essential information not available from a public source, in which case the name of the person and date of communication should be cited in parentheses in the text. Authors should obtain written permission and confirmation of accuracy from the source of a personal communication. Provide complete information for each reference. If the reference is to part of a book, also include the title of the chapter and name(s) of the book’s editor(s). Reference to electronic documents that can found on the internet should be accompanied with their URL, and the date last visited.

Illustrations (including legends). Must be numbered and cited in the text in order of appearance and submitted electronically (at least 300 dpi). Legends for illustrations should use Arabic numerals corresponding to the illustrations. When symbols, arrows, numbers, or letters are used to identify parts of the illustrations, identify and explain each one clearly in the legend. Provide the correct magnification when needed.

Tables. Number tables consecutively in the order of their first citation in the text and supply a brief title for each. Do not use internal horizontal or vertical lines. Give each column a short or abbreviated heading. Authors should place explanatory matter in footnotes, not in the heading. Explain in footnotes all nonstandard abbreviations. Identify statistical measures of variations, such as standard deviation and standard error of the mean. If you use data from another published or unpublished source, obtain permission and acknowledge them fully.  This journal strongly encourages authors to make detailed data accessible to other researchers (tables with individual patient data are welcome).
