EGFR and peripheral vascular disease: The statistically significant variables were introduced in a multivariate logistic regression analysis, where the variables that remained associated with the outcome were: hypertension (OR 1.883 (1.086–3.265), p = 0.024), EGFR < 60 mL/min (2.365 (1.375–4.070), p = 0.002), and peripheral vascular disease (4.66(2.134–10.177), p < 0.001).
