Acknowledgments

The source of any financial support received and recognition of personal assistance for the work being published should be indicated at the end of the article, just before the Reference section, under the heading Acknowledgments. Collate acknowledgments in a separate section at the end of the article before the references and do not, therefore, include them on the title page, as a footnote to the title or otherwise. List here those individuals who provided help during the research (e.g., providing language help, writing assistance or proof reading the article, etc.).

Figure Captions

  • Figures include photographs or radiographs, drawings, graphs, bar charts, flow charts, and pathways, but NOT lists or tables.
  • Figures must be cited sequentially in the text. Number all figures (and corresponding figure captions) sequentially in the order they are cited in the text.
  • Figure captions should be written after the reference list. Insert a page break between the end of references and the start of figure captions.
  • Figure captions should include a description of the figure and/or each lettered part (A, B, etc.) and of any portions of the figure highlighted by arrows, arrowheads, asterisks, etc.
  • For a figure borrowed or adapted from another publication (used with permission), add a credit line in parentheses at the end of each figure legend. This credit line should be a complete bibliographic listing of the source publication (as a reference), or other credit line as supplied by the copyright holder. For example (Reprinted with permission from Calfee DR, Wispelwey B. Brain abscess. Semin Neurol 2000;20:357.)

Tables

  • Data given in tables should be commented on but not repeated in the text. Be sure that lists or columns of related data are composed in a word-processing program like the rest of the text.
  • Do not intersperse tables in the text. Tables should appear after the figure captions. Insert a page break between the end of the figure captions and the start of the tables.
  • Tables must be double-spaced and numbered in the same sequence they are cited in the text. A short descriptive title should be provided for each table.
  • If a table contains artwork, supply the artwork separately as a digital file.
  • For tables borrowed or adapted from another publication (used with permission), add a credit line as the first footnote beneath each table. This credit line should be a complete bibliographical listing of the source publication (as a reference), or other credit line as supplied by the copyright holder. For example, “Reprinted with permission from Calfee DR, Wispelwey B. Brain abscess. Semin Neurol 2000;20:357.” (“Data from ...” or “Adapted from ...” may also be used, as appropriate.)
  • Other footnotes for tables should be indicated in the table using superscript letters in alphabetical order.
  • Any abbreviations used in the table should be explained at the end of the table in a footnote.

Digital Artwork Preparation

  • It is best to use Adobe Photoshop to create and save images, and Adobe Illustrator for line art and labels.
  • Do not submit art created in Microsoft Excel, Word, or PowerPoint. These files cannot be used by the typesetter.
  • Save each figure in a separate file.
  • Do not compress files.
  • All black-and-white and color artwork should be at a resolution of 300 dpi (dots per inch) in TIFF format. Line art should be 1,200 dpi in EPS or TIFF format. Contact the Production Editor at Thieme if you are unsure of the final size.
  • It is preferable for figures to be cropped to their final size (approximately 3 inches for a single column and up to 7 inches for a double column), or larger, and in the correct orientation. If art is submitted smaller and then has to be enlarged, its resolution (dpi) and clarity will decrease.

Note: Lower resolutions (less than 300 dpi) and JPEG format (.jpg extension) for grayscale and color artwork are strongly discouraged due to the poor quality they yield in printing, which requires 300 dpi resolution for sharp, clear, detailed images. JPEG format, by definition, is a lower resolution (compressed) format designed for quick upload on computer screens.

Black-and-White Art

  • Black-and-white artwork can be halftone (or grayscale) photographs, radiographs, drawings, line art, graphs, and flowcharts. Thieme will only accept digital artwork.
  • If possible, do not send color art for conversion to black-and-white. Do the conversion yourself so that you can check the results and confirm in advance that no critical details are lost or obscured by the change to black-and-white.
  • For best results, line art should be black on a white background. Lines and type should be clean and evenly dark. Avoid screens or cross-hatching, as they can darken or be uneven in printing and lead to unacceptable printing quality.

Color Art

  • All color artwork should be saved in CMYK, not RGB.

Art Labels

  • Arrows, asterisks, and arrowheads (or other markers) should be white in dark or black areas and black in light or white areas, and large in size. If not, these highlighting marks may become difficult to see when figures are reduced in size during the typesetting process.
  • Use 1-point (or thicker) rules and leader lines.
  • Capitalize the first word of each label and all proper nouns. Consider using all capitals if you need a higher level of labels.
  • Where there are alternate terms or spellings for a named structure, use the most common one and make sure it is consistent with what is used in the text.
  • Avoid using multiple fonts and font sizes for the labels; use only one or two sizes of a serif font.

Forms must be submitted even if there is no conflict of interest. It is the responsibility of the corresponding author to ensure that all authors adhere to this policy prior to submission. A conflict of interest statement must also be included in the manuscript after any "Acknowledgments" and "Funding" sections and should summarize all aspects of any conflicts of interest included on the ICMJE form. If there is no conflict of interest, authors must include 'Conflict of Interest: none declared'. Please click http://www.icmje.org/conflicts-of-interest to download a Conflict of Interest form. The disclosure information is important in article processing. If the provided forms are incomplete or missing, it can cause delays in publishing of article.

Informed Consent

The journal adheres to the principles set forth in the Helsinki Declaration and holds that all reported research conducted with human participants should be conducted in accordance with such principles. Reports describing data obtained from research conducted in human participants must contain a statement in the Methods section indicating approval by the Institutional Review Board (IRB). The authors should also indicate whether or not individual consent for the study was obtained, or whether it was waived.

Conflicts arising from papers authored by Editorial Board Members

The journal evaluates any submissions from the members of the editorial board purely on merit of the clinical content presented as it does for any other article coming from authors globally. All the articles including articles from Editorial Board members are evaluated via double-blind peer review process, which will ensure that the information of author(s) is not revealed to the reviewers. In doing so, the journal ensures there are no conflict of interests or preferences and selection of articles is purely on its clinical content merit, thus ensuring best ethical standards and practices of peer-review are maintained.
