Survival and associated risk factors in patients with diabetes and amputations caused by infectious foot gangrene

Table 3 Multivariate logistic regression analysis of risk factors to predict major LEA in the patients with infectious foot gangrene

Factors⁺	Interpretation	Odds ratio	95% confidence interval	P value
Abnormal ABI	Yes vs. No	3.12^*	1.18–8.24	0.02
Age	Every 1 year increment	0.97	0.93–1.02	0.21
Diabetes duration	Every 1 year increment	0.99	0.94–1.04	0.66
Smoking status	Yes vs. No	0.54	0.19–1.53	0.25
Hypertension	Yes vs. No	1.28	0.53–3.10	0.59
MACE history	Yes vs. No	1.13	0.45–2.80	0.80
CKD (eGFR < 60)	vs. normal renal function (eGFR ≥60)	1.81	0.74–4.46	0.20
Dialysis	vs. normal renal function (eGFR ≥60)	2.51	0.71–8.85	0.15
HbA1c	Every 1% increment	0.95	0.81–1.13	0.58

^*Significance: P value <0.05
⁺Including the continuous variable of age, diabetes duration and HbA1c; and categorical variables of smoking status, hypertension, major adverse cardiac events, ankle-brachial index, and renal function
LEA lower-extremity amputation, ABI ankle-brachial index, MACE major adverse cardiac event, CKD chronic kidney disease, eGFR estimated glomerular filtration rate
