Sensitivity analysis for the association of surgical delay and overall survival in multivariable Cox proportional hazard models for the entire cohort and a subgroup of patients with CCI = 0. Surgical delay is treated as an unordered categorical variable in model 1 and a continuous variable in model 2. Overall survival was calculated as the interval from diagnosis to either death or last clinical contact
