CRP and diabetes mellitus: The multivariate logistic regression analysis subsequently revealed advanced age (p < 0.001, OR (95%CI) 1.050 (1.040–1.061)), increased CRP (p < 0.001, OR (95%CI) 1.010 (1.007–1.014)), the presence of diabetes (p < 0.001, OR (95%CI) 2.386 (1.933–2.946)), and heightened WMR (p < 0.001, OR (95%CI) 2.258 (1.460–3.492)) as significant predictors for CLTI (Table 2).
