INS and Insulin resistance: A correlation occurred between age and fasting blood glucose (rs= 0.37, p=0.045, Figure 1A) but fasting blood insulin levels and HOMA-IR index (an index of insulin resistance) were not significantly correlated with age (fasting insulin, rs=0.03, p=0.84; HOMA-IR: rs=0.22, p=0.28; Figure 1B, Table 1).
