MHNO Metabolically healthy non-obesity; MHO Metabolically healthy obesity; MANO Metabolically abnormal non-obesity; MAO Metabolically abnormal obesity; BMI Body mass index; SBP Systolic blood pressure; DBP Diastolic blood pressure; FPG Fasting plasma glucose; HDL High-density lipoprotein. Data are the % (number), mean ± standard deviation, or median (interquartile range). The analyses of continuous variables to assess differences among the four groups were performed using one-way ANOVA or Kruskal-Wallis Test, followed by Tukey’s Honestly Significant Difference Test or Steel-Dwass Test. The analyses of categorical variables among the four groups were determined by Pearson’s Chi-Squared Test. *, p < 0.05 vs. MHNO; †, p < 0.05 vs. MHO; and ‡, p < 0.05 vs. MANO
