In Model 3, heart failure, ALB, Cr, and RDW were further included as covariates, and it was similarly found that CBC-derived inflammatory markers were positively correlated with diabetic foot: MLR (OR: 4.55, 95%CI: 1.37–14.02, P = 0.010); NLR (OR: 1.12, 95%CI: 1.00–1.25, P = 0.035); NMLR (OR: 1.12, 95%CI: 1.01–1.24, P = 0.030); SIRI (OR: 1.25, 95%CI: 1.06–1.46, P = 0.006). The gene discussed is ALB; the disease is heart failure.
