The muscle mass (r = 0.079 in men; r = 0.032 in women) and muscle percentage (r = 0.049 in men; r = 0.053 in women) were positively correlated with the IFN-γ levels, whereas the fat percentage (r = −0.050 in men; r = −0.053 in women), WBC count (r = −0.169 in men; r = −0.225 in women), CRP level (r = −0.037 in men; r = −0.059 in women), insulin level (r = −0.048 in men; r = −0.046 in women), and homeostasis model assessment of insulin resistance (HOMA-IR) (r = −0.045 in men; r = −0.039 in women) were negatively correlated with the IFN-γ levels in both men and women. The gene discussed is INS; the disease is Insulin resistance.
