Effect of melatonin on fasting plasma glucose, serum transaminase, and lipid levels. (a) Fasting plasma glucose (FPG, mmol/L), *P < 0.05 vs group A. (b) Alanine aminotransferase (ALT, IU/L) and aspartate aminotransferase (AST, IU/L). *P < 0.05 vs other 3 groups. (c) Triglycerides (TG, mmol/L), low-density cholesterol (LDL-C, mmol/L) and high-density cholesterol (HDL-C, mmol/L). *P < 0.05 for group A vs group B; #P < 0.05 for group B vs group D
