IGF1 and type 2 diabetes mellitus: Among T2DM patients, serum IGF-1 levels were positively correlated with muscle strength (r = 0.255, P < 0.01) and muscle mass (r = 0.209, P < 0.05), levels of 8-OHdG were inversely correlated with muscle strength (r = −0.252, P < 0.01), and there was a negative association between HCY and muscle mass (r = −0.185, P < 0.05).
