What was measured
Duration of time from randomization to the first indication of invasive breast recurrence at a distant site. In the absence of an event, DRFI was censored at the date of last follow-up visit or date or death without distant recurrence.\* \*This endpoint replaced DDFS, which was specified in the protocol
Analysis population: Intention-to-treat
Groups in this outcome

Continuous letrozole: 5 years continuously (2.5 mg Letrozole daily) Letrozole: Film-coated tablet, oral use, 2.5 mg Letrozole daily for 5 years continuously
