a
Coefficients were derived with imputation of missing data and adjustment for confounders, including recruitment site (fixed-effect), age, sex, American Society of Anesthesiologists score, colon vs rectal surgery, minimally invasive vs open surgery, baseline 6-minute walk test, body mass index, and Fried Frailty Index (2-3 vs 4-5). No data were missing for the variables described, so imputation was conducted only for adjustment variables. The multiple imputation model is described in eMethods 3 in Supplement 2.
