Finding: At the second interim analysis of overall survival (58% maturity), overall survival did not significantly differ between the groups (HR 0·88 [95% CI 0·64–1·21]; p=0·44); similar findings were noted for patients with mutated  BRCA  (HR 0·73 [0·45–1·17]; p=0·19) and wild-type  BRCA  (HR 0·99 [0·63–1·55]; p=0·96).
Certainty (1-5): 5
