PFR associated with the presence of DPN in logistic regression (enter method).

	PFR
	β (s.e.)	OR (95% CI)	P-value
M1	−0.517 (0.107)	0.596 (0.483–0.736)	< 0.001
M2	−0.336 (0.117)	0.715 (0.568–0.899)	0.004
M3	−0.328 (0.120)	0.720 (0.570–0.911)	0.006
M4	−0.359 (0.121)	0.698 (0.550–0.886)	0.003
M5	−0.478 (0.178)	0.620 (0.437–0.879)	0.007

Data are presented as regression coefficient (standard error), odds ratio (95% CI) and P-value. Logistic regression analysis (enter method) was used to evaluate the association of PFR and DPN after adjusting other clinical and biochemical variables. Bold indicates statistical significance (P < 0.05).

M1 is a regression model including just PFR; M2 adds age, duration and HTN to the predictors of M1; M3 adds FPG and TC to the predictors of M2; M4 adds Crea to the predictors of M3; M5 adds NLR and AFR to the predictors of M4.
