  1. aOR Adjusted odds ratio. CI Confidence interval. *Significant association, p < 0.05. The final multivariate model controlled for the following confounding variables: age, sex, physical component score, dialysis duration, retinopathy, ischemic heart disease, C-reactive protein, serum albumin, serum phosphate, glycated hemoglobin, peripheral neuropathy, peripheral arterial disease, inappropriate/ill-fitting footwear, nail pathology, and podiatry attendance
