General Guidelines
• You must submit a digital copy of your manuscript. Hard copy submissions are not accepted.
• Keep the format of your manuscript simple and clear. We will set your manuscript according to our style—do not try to “design” the document.
• The manuscript, including the title page, abstract and keywords, text, references, figure captions, and tables should be typewritten, double-spaced in 12-point font with 1-inch margins all around and saved as one file.
• Each figure should be saved as its own separate file. Do not embed figures within the manuscript file. This requires special handling by Thieme’s Production Department.
• Keep abbreviations to a minimum and be sure to explain all of them the first time they are used in the text.
• The manuscripts should be written in American English.
• The authors should use Système International (SI) measurements. For clarity, nonmetric equivalents may be included in parentheses following the SI measurements.
• Use generic names for drugs. You may cite proprietary names in parentheses along with the name and location of the manufacturer.
• Credit suppliers and manufacturers of equipment, drugs, and other brand-name material mentioned in the manuscript within parentheses, giving the company name and primary location.

Title Page
• This journal adheres to a single-blinded peer-review policy. The title page should be included in the main document.
• The title page should list the article title and the corresponding author’s full name, degree, title, department, affiliation, mailing address, e-mail address, and telephone and fax numbers. It should also list the full name, degree, title, department, and affiliation of every co-author.
Abstract and Keywords
See the section Article Types for word limits.
The abstract should briefly outline the content of the article and any conclusions it may reach. It should be structured as follows: Objective, Study Design, Results, Conclusion. The keywords should be words a reader would be likely to use in searching for the content of the article.
Key Points
• 3 to 5 key points should be supplied.
• Please limit the length of each key point to 50 characters or less
Main Document
• Please clearly distinguish the hierarchy of headings within the manuscript by using capital letters, underline, italic, and bold styles as necessary.
• As needed, use italic, superscripts, subscripts, and boldface, but otherwise do not use multiple fonts and font sizes.
• Do not insert page or section breaks except where noted in the Author Instructions.
• Use hard returns (the Enter key) only at the end of a paragraph, not at the end of a line. Allow lines of text to break automatically in your word-processing software. Do not justify your text.
• Use only one space, not two, after periods.
• Create tables using the Table function in Microsoft Word.

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.
Conflict of Interest
All authors (including corresponding and co-authors associated with the manuscript) must make a formal statement at the time of submission indicating any potential conflict of interest that might constitute an embarrassment to any of the authors if it were not to be declared and were to emerge after publication. Such
conflicts might include, but are not limited to, shareholding in or receipt of a grant or consultancy fee from a company whose product features in the submitted manuscript or which manufactures a competing product. Should the article be accepted for publication, this information will be published with the paper.
Types of conflicts include: Consulting, Royalties, Research Support, Institutional Support, Ownership, Stock/Options, Speakers Bureau, and Fellowship Support. Any commercial entity whose products are described, reviewed, evaluated, or compared in the manuscript, except for those disclosed in the Acknowledgments section, are potential conflicts.
This journal follows the guidelines of the International Committee of Medical Journal Editors and an ICMJE disclosure of potential conflicts of interest (COI) form must be submitted for each author at the time of manuscript submission. 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 "Acknowledgements" 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.

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
General Guidelines
• 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 3½ 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
• Color illustrations are expensive to produce and usually cannot be accepted unless the author is willing to cover the additional production costs incurred. Please check with the Editor in Chief or Thieme for details. We will convert color illustrations to black-and-white unless we receive a letter from the author assuming responsibility for the cost of printing color. Upon request, we will provide you with a cost estimate for the color printing.
• 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.
