Values in parentheses are 95% confidence intervals. The survival probabilities were obtained using multivariate Cox regression models to perform direct standardization. The corresponding confidence intervals were obtained using a normal approximation, where the asymptotic variance was estimated using the influence function. CME, complete mesocolic excision.
