Time to Definitive Deterioration in the All-Comer Populationa. aDatabase cutoff: 26th October 2020. bTime to definitive deterioration is defined as the time from first dose of treatment to first onset of ≥10 points decrease from baseline for functional scales (decrease of ≥7 points for the for VAS 7-point threshold) and ≥10 points increase for symptom scales from baseline without subsequent recovery or no subsequent assessment data; a longer time to deterioration is considered more favourable. cNumber of patients in the HRQoL full analysis set with available data. dFrom product-limit (Kaplan-Meier) method for censored data. eBased on Cox regression model with treatment as a covariate stratified by MMR status, ECOG PS, geographic region, and prior history of pelvic radiation. fTwosided P value using Wald test (score test in case of zero event in 1 treatment group).
