- Data are expressed as mean ± standard deviation, unless otherwise indicated. BP, blood pressure; HDL; high-density lipoprotein, FBG, fasting blood glucose; HOMA-IR; homeostatic model assessment for insulin resistance, eGFR; estimated glomerular filtration rate.
- eGFR was calculated using the 6-variable Modification of Diet in Renal Disease (MDRD) formula.
- * p-values for analysis of variance (ANOVA) and chi-square tests for trends are shown, as appropriate.
