 Alanine aminotransferase (ALT; U/L) 27.5 (IQR = 23.75), 46 0–241 32.6% (10–45)
Cholesterol Panel
 Cholesterol (mmol/L) 3.65 (SD = 0.89), 24 1.3–5.2 16.7% (2.6–5.2)
 Triglycerides (mmol/L) 0.70 (IQR = 0.72), 23 0.24–2.12 26.1% (0.4–1.5)

  1. aMean (Standard Deviation) is reported for variables that were normally distributed. Median (Interquartile Range) is reported for variables with a non-normal distribution
  2. b3 males had undetectable testosterone levels. The values presented are for those for whom hormone levels could be recorded by the laboratory (n = 27); however, the column for the percentage of participants for whom the values were out of range included those who had undetectable testosterone levels
