  1. HOMA-IR, homeostasis of minimal assessment of insulin resistance. Data for fasting blood glucose, fasting insulin, and HOMA-IR were skewed, and are presented as median (interquartile range). §HOMA-IR was calculated using the following formula; {fasting blood glucose (FBG) (mg/dL) X fasting Immunoreactive insulin (mU/mL)}/405. Data for fasting blood glucose, fasting insulin, and HOMA-IR were log-transformed for analysis. *Student's t test or χ2 test.
