  1. SUVmean/max, mean/maximum standardized uptake value; TBRmean/max, mean/maximum target-to-background ratio; BP, blood pressure; FPG, fasting plasma glucose; HbA1c, glycated hemoglobin A1c; HDL, high density lipoprotein; LDL, low density lipoprotein; AST/ALT, aspartate/alanine aminotransferase; CRP, C-reactive protein. Data are presented as Pearson’s correlation coefficient (r). p < 0.05 was regarded as statistically significant.
