What was measured

Time from randomisation to first subsequent anti-cancer therapy (FST) following randomised treatment discontinuation, or death if no FST administered. Any patient not known to have died nor received any subsequent anti-cancer therapy (ST) was censored at the last time known not to have received ST, ie, the last follow-up visit this was confirmed.
