  1. Clinically relevant significant and non-significant correlation coefficients in the whole study population and in T2D subjects and NGT subjects. Data are presented as r: correlation coefficient of correlation, and the sample size and P-value in parentheses. NGT, normal glucose tolerant subjects; T2D, type 2 diabetes subjects; BMI, body mass index; HbA1c, glycated hemoglobin; HOMA-IR, homeostasis model assessment of insulin resistance. Data are analyzed by Spearman correlation test, P < 0.05.
