Survival by aspirin use. A) Event-free survival. B) Distant disease–free survival. C) Overall survival. Each graphic is a Kaplan-Meier survival plot for 476 women who used low-dose aspirin and 1733 women who did not. At a median follow-up of 4.1 years, the 476 aspirin users had 72 (15.1%) event-free survival events, while the nonusers had 177 (10.2%) events (stratified log-rank P = .006); those who used aspirin experienced 21 (4.4%) distant disease–free survival events, while those who did not had 87 (5.0%) events (P = .72), and those who used or did not use aspirin had, respectively, 56 (11.8%) and 110 (6.4%) deaths from any cause (P < .001).
