RETN and peripheral arterial disease: Adjustment of the factors significantly associated with PAD (smoking, age, Cre, eGFR, hs-CRP, and resistin) on multivariate logistic regression analysis revealed that increased serum resistin level (odds ratio [OR], 1.176; 95% confidence interval [CI], 1.028–1.345; p = 0.018) was an independent predictor of PAD in hypertensive patients (Table 4); plotting of the ROC curve for PAD prediction revealed that the AUC for resistin was 0.870 (95% CI, 0.798–0.923; p < 0.001) (Fig. 1).
