Analysis of secondary outcomes The analyses of the seven scales from EORTC QLQ-C30 (physical function, role function, emotional function, nausea and vomiting, pain, dyspnoea, or lack of appetite) will be made using the same principles as described for the primary outcome including the sensitivity analyses. Survival will be analysed using Kaplan-Meier plot. Patients who are alive three months after the end of data-collection will be censured on this date. A Cox regression will be made adjusted for the stratification variable. A sensitivity analysis will be made adjusting for all relevant covariates.
