Tables: All tables should be created with the 'insert table' function of Microsoft Word. Do not format the table for style. The tables should be cited in numerical order in the text in bold font (Table 1, Table 2 etc.). Each table should have a table number and a descriptive title above the table. Explanations for abbreviations and levels of significance should be given at the bottom of the table as letters in superscript (for example a, b, c etc.), not as symbols (for example @, # etc.). 

Figures and figure legends: All illustrations are referred to as "Figures" and must be numbered consecutively in bold font, for example (Figure 1, Figure 2 etc.). Figures should be high resolution TIFF images. They must be inserted using the 'insert picture' function of the Microsoft Word. Include figure legends immediately below respective figures. Figure legend should have the figure number, a short title, and a stand-alone description of the figure. Symbols, arrows, or letters used in images should contrast with the background. Explain the internal scale and identify the method of staining in photomicrographs (if relevant).

Note 1: Multi-panel images should be inserted as a single image, not as separate images. For example, Figure 1 a, b and c should be made into a single TIFF image in Photoshop or any appropriate software and inserted as a single image.

Note 2: Apart from inserting into the Microsoft Word, TIFF images should be uploaded separately at 'step 4' of the submission process.

Supplementary data: No supplementary data are allowed for review articles. 

Units: Measurements of length, height, weight, and volume should be reported in metric units (meter, kilogram, or liter) or their decimal multiples. Temperatures should be in degrees Celsius. Blood pressure should be in millimeters of mercury.

Abbreviations: Abbreviations should be spelled-out on first mention followed by the abbreviation in parenthesis.
