  1. CVD, cardiovascular disease; HDL, high-density lipoprotein; LDL, low-density lipoprotein; HMW. High molecular weight; hsCRP, high sensitivity C-reactive protein. Data presented are mean ± standard deviation. Data for triglycerides, fasting plasma glucose, HMW adiponectin, Immuno-reactive insulin, and hsCRP were skewed, and are presented as median (interquartile range) and were log-transformed for analysis. *P-value: ANOVA or X2 -test.
