Abbreviations: CI=confidence interval; ECOG=Eastern Cooperative Oncology Group; HR=hazard ratio; NA=not available; PS=performance status.
a
Hazard ratio and 95% CI calculated by Cox-proportional hazards models; models adjusted for sex, age, physician-assigned PS and cancer type.
b
Models did not run due to an empty cell in this category.
