  1. aOR Adjusted odds ratio. CI Confidence interval. *Significant association, p < 0.05. SD Standard deviation. The final multivariate model controlled for the following confounding variables: age, sex, living alone, dialysis duration, diabetes mellitus, serum phosphate, previous foot ulceration and podiatry attendance
