Histograms defining normal values for ALT and AST by gender in 371 healthy students.

<p>Histograms defining normal values for ALT and AST by gender in 371 healthy students.</p

Factors correlated with ALT level in 925 students.

<p>Abbreviations: BMI: Body mass index; HOMA-IR: homeostasis model assessment of insulin resistance; DBP: diastolic blood pressure; SBP: systolic blood pressure; T-C: Total cholesterol; TG: Triglyceride.</p

95^th percentile, predicted and 5th percentile of ALT values by age for females.

<p>The X axis represents current student age. The Y axis is the ALT level, and the top and bottom lines are the 95^th and 5^th percentile. The middle line represents the predicted values for ALT in female participants according to age.</p

Baseline characteristics of the total cohort and the ‘healthy’ population.

<p>Abbreviations: ALT: alanine aminotransferase, AST: aspartate aminotransferase, BMI: body mass index, HOMA-IR: homeostasis model assessment of insulin resistance, LDL: low-density lipoprotein, SD: standard deviation, T-C: Total cholesterol, TG: Triglyceride.</p
