(<23, 23≤ BMI<28, and ≥28). Data are shown in real case numbers. All variables except the occurrence of metabolic complication distribute equally among the three groups. The χ2 and P values are determined by Linear-by-Linear Association two-tailed Chi-square test or Fisher’s exact test. The symbol * represents statistical significance (P < .05).
