Notes: *p<0.05; **p<0.01. Model1: Age; Duration; FPG; HbA1c; SBP and TG are forced to enter the model; and other indicators are entered by stepwise (p<0.05 entered; p>0.1 removed). Model2: Model1 +TCSS score (Age; Duration; FPG; HbA1c; SBP and TG are forced to enter the model; other indicators are entered stepwise; p<0.05 entered; p>0.1 removed) (a is removed from Model3). Model3: CV; Amp and DML of Model1 + median nerve¹; ulnar nerve²; common peroneal nerve³ and tibial nerve⁴ (Age; Duration; FPG; HbA1c; SBP and TG were forced into the model; and other indicators were entered by stepwise. p<0.05 entered; p>0.1 removed) (b is removed from Model2).
