Fine-gray competing risks regression analyses of factors associated with diabetic foot ulcer healing

Variable	Fine-Gray SHR (95%CI)	P value
Wagner grade 5 (vs. grade 4)	0.17 (0.08–0.40)	< 0.001
Peripheral artery disease	0.51 (0.30–0.89)	0.017
Age (per year)	0.99 (0.97–1.02)	0.52
Male (vs. female)	1.18 (0.63–2.20)	0.60
DFU duration (per week)	1.00 (0.99–1.00)	0.18
Intervention (vs. control)	1.74 (1.08–2.83)	0.024

Abbreviations: SHR, subdistribution hazard ratio; CI, confidence interval. Fine‑Gray model treated major amputation and death as competing events. Multivariable model included all listed variables
