WIFI: Wound, Ischemia, Foot infection Classification."Reference", indicates the reference category used for comparison in the regression model.
*Regression model includes all associated factors with p < 0.2 in the crude analysis (time from admission to initial debridement, WIFI classification categories, longer wound length, osteomyelitis, and type of definitive treatment).
