  1. NWL, normal weight lean; NWO, normal weight obesity; N, number; BP, blood pressure; 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 mean ± SD or number (percentages). The p values represent differences between groups determined by an independent two-sample t-test for continuous variables and the χ2 test or the Fisher’s exact test for categorical variables.
