BMI, body mass index; SBP, systolic blood pressure; DBP, diastolic blood pressure; HDL-C, high-density lipoprotein cholesterol; LDL-C, low-density lipoprotein cholesterol; hsCRP, high sensitivity C-reactive protein; HOMA-IR, homeostasis model assessment insulin resistance; VFA, (abdominal) visceral fat area; SFA, (abdominal) subcutaneous fat area; PAT, pericardial adipose tissue.
Data are mean ± SD, median (interquartile range), or N (%).
Means or medians with the different letter are significantly different.
The variables expressed as medians (interquartile range) were assessed by the the Mann-Withney test in multiple comparisons, and the P-values were adjusted by the Bonferoni correction (P <0.017 was considered statistically significant).
P’ values were calculated after adjusting for age and sex by using the analysis of covariance (ANCOVA) for continuous variables and a logistic regression analysis for categorical variables.
