  1. Factors with an eigenvalue ≥ 1 were selected for analysis. * Factor loadings ≥ |0.40|. a Factor loadings are calculated after varimax rotation of variables in each extracted factor. b Log transformed.
  2. Abbreviations: HOMA-IR, homeostasis model assessment of insulin resistance; TG, triglycerides; HDL-C, high density lipoprotein cholesterol; TG/HDL-C, triglycerides to HDL-C ratio; SBP, systolic blood pressure.
