Data are expressed as mean (standard deviation) for normally distributed data, median (25th percentile, 75th percentile) for non-normally distributed data or proportion (%) for categorical data. Independent t-test (normally distributed data), Mann-Whitney test (non-normally distributed data) or chi-square test (categorical data) were used to compare differences between MHO and MUO children. MHO, metabolically healthy obese; MUO, metabolically unhealthy obese; BMI, body mass index; WC, waist circumference; HOMA-IR, homeostasis model assessment of insulin resistance; LDL-cholesterol, low-density lipoprotein-cholesterol; hsCRP, high-sensitivity C-reactive protein; ALT, alanine transaminase; AST, aspartate transaminase; NAFLD, non-alcoholic fatty liver disease; GGT, gamma-glutamyl transferase; eGFR, estimated glomerular filtration rate; CKD, chronic kidney disease; SD, standard deviation; q25, 25th percentile; q75, 75th percentile
