Letters, numbers, and symbol s should be elear and even throughout and of sufficient size that when reduced for publication each Hem will still be legible.

Describe the specific tests used to examine each part or the results. Care should be taken with respect to a) parametric vs. non-parametric data, b) correetions for multi ple eomparisons, and e) rounding errors (summary statistics should not contain more significant digits the original data). Variability should be expressed either as median and range (or percentiles) for nonpara-metric data,or mean ± standard error, standard deviation (or confidence intervals) for normally distributed data. Traditionally FOLIA MEDlCA uses the following symbols: X±SX (for mean and standard error) and Sx (for standard deviation).
UNITS OF MEASUREMENT.Ali measurements should be reported in aeeordanee with the International System or Units (SI).
ABBREVIATIONS. Use only standard abbreviations. Avoid abbreviations in title and abstract. The full term for which an abbreviation stands should preeede its first use in the text unless it is a standard unit or measurement.
