Data are shown as medians (interquartile range); WHR: waist/hip ratio, TBW: total body water, PBF: percentage of body fat, FFA: free fat mass, SMM: skeletal muscle mass, and BMR: basic metabolic rate; differences between groups were tested by Mann-Whitney test; : between IgG4-HT and non-IgG4-HT; : between IgG4-HT and control group.
