There were differences in the following baseline characteristics between the diabetic foot group and the control group: heart failure(HF) (P = 0.037), albumin (ALB) (P < 0.001), serum creatinine (Cr) (P < 0.001), red blood cell distribution width (RDW) (P = 0.004), NLR (P = 0.003), MLR (P = 0.013), NMLR (P = 0.002), and SIRI (P = 0.006). This evidence concerns the gene ALB and heart failure.
