From: Surgical revascularization versus amputation for peripheral vascular disease in dialysis patients: a cohort study

  30 day mortality 1 year mortality
  Odds ratio* (95%CI) Odds ratio* (95%CI)
Entire cohort (n = 3942)   
   Unadjusted 2.00 (1.64–2.44) 1.67 (1.48–1.90)
   Adjusted** 1.85 (1.45–2.36) 1.46 (1.25–1.71)
Subgroup analyses by likelihood for amputation***   
   Low likelihood group (n = 1314) 1.85 (1.06–3.23) 1.61 (1.14–2.26)
   Moderate likelihood group (n = 1314) 2.05 (1.47–2.87) 1.55 (1.22–1.96)
   High likelihood group (n = 1314) 1.56 (0.91–2.21) 1.23 (0.92–1.63)
  1. *reference revascularization group
  2. **adjusted for propensity scores, demographics (age, sex, race), dialysis modality, comorbid conditions (diabetes, coronary artery disease, congestive heart failure, cerebrovascular disease and malignancy), clinical indications (intermittent claudication, resting pain, ulcer, gangrene or other/unknown), hematocrit, nutritional status (BMI and serum albumin) and functional status (required assistance to transfer or ambulate).
  3. ***adjusted for all above variables except propensity score
