Cox proportional hazards models for 1-year complete foot healing and limb salvage outcomes stratified by quartile of estimated benefit of revascularization

	HR (95% CI)
Outcome	Q1 (highest benefit)	Q2 (moderate benefit)	Q3 (low benefit)	Q4 (questionable benefit)
Major amputation	Reference	0.65 (0.11-3.91)	1.03 (0.17-6.15)	4.26 (1.15-15.7)
Complete foot healing	Reference	1.06 (0.67-1.67)	1.34 (0.80-2.25)	0.61 (0.35-1.05)
Loss of patency	Reference	1.04 (0.35-3.11)	1.59 (0.54-4.74)	2.45 (0.87-6.90)
Loss of amputation-free survival	Reference	0.89 (0.36-2.19)	0.46 (0.13-1.68)	1.44 (0.60-3.47)
