Manuscript preparation: Hippokratia Journal complies with the Uni­form Requirements for Manuscripts by the International Committee of Medical Journal Editors. Articles submitted for publication should be written in English language. The copy-editor of the journal has the right to change the language structure of the manuscript without transforming its meaning by the author. Number pages consecutively in this order: title page, abstract, text, refer­ences, legends, and tables. Figures should be provided separately.

a. On the title page provide the title of the article, list each author’s name and institutional affiliation, and indicate the corresponding author. In case, the study has been reported in abstract form elsewhere, indicate the respective scientific meeting.

b. On the abstract page provide the abstract (background, methods, re­sults, conclusions) and 3-7 key-words.

c. Figure and Table preparation. Figures: For reproduction in the journal you will be required, to sup­ply high resolution .tiff images in separate files (1200 dpi for line drawings and 300 dpi for color and half tone work at intended dis­play size – column width of 76 mm or page width of 160 mm). It is advisable to create your high resolution images first as they can easily converted into low resolution images for on line submission. Line drawings, graphs, and charts should be professionally drawn or computer generated and printed on a high resolution laser printer. Any lettering in the figures should be large enough to stand photographic reduction. Authors should prepare their figures for either one column (76 mm) or the entire page width (160 mm). The editors reserve the right to reduce the size of illustrated material. Authors may, however, specifically request a larger reproduction.

Figures should be numbered consecutively with Arabic numerals, in the order in which they appear in the text. Reference should be made in the text
to each figure. Each figure must be accompanied by an explanatory legend, typewritten with double spacing and the legends to all figures should be
typed together on a separate sheet at the end of the manuscript. Any photomicrographs, electron micrographs or radiographs must be of high quality. Photomicrographs of histopathological specimens should provide details of staining technique and magnification used (or use an internal scale bar). All micrographs must carry a magni­fication bar. Explain all symbols used in the figure. Patients shown in photographs should have their identity concealed or should have given their written consent to publication of the photographs. For a photograph of a minor, signed parental permission is required.

Tables should be added at the end of the manuscript and not interspersed throughout the manuscript. They should be submitted as part of the Word document, typed neatly, each table on a separate page in double spacing, with the title above and a clear legend below. The legend should contain all the necessary information so that the table and legend may stand alone, independent of the text. Explain all abbreviations. Stan­dard abbreviations of units of measurement should be added between parentheses. A table must have at least two columns. Column headings should be brief, but sufficiently explanatory. Lists are to be incorporated into the text. Do not use patient initials in tables. Patients should be referred to by sequential Arabic numerals, not by their initials.

d. References: Use et al after the 6th author name. Put a full stop after the journal’s name and after the last page. Refer year (;), volume (:), and first and last page. The author is responsible for obtaining written permission to repro­duce previously published material (illustrations, tables) from the copyright holder. The consent of the senior author must also be ac­quired.
