RETN and hyperinsulinism: This was associated with hyperleptinemia (F(1,10) = 266.2, p<0.0001), hyperinsulinemia (F(1,10) = 21.1, p<0.001), hyperglycemia (F(1,8) = 14.3, p<0.005) and hypercortisolemia (F(1,10) = 11.4, p<0.01), but reduced plasma concentrations of resistin (F(1,10) = 13.4, p<0.005) (Table 1).
