Fig. 3From: The association of aspirin use with overall survival of patients with inoperable non-small cell lung cancer: a retrospective studySubgroup analysis of adjusted hazard ratios (HRs) of risk factors for aspirin-related mortality. Aspirin use was associated with a significantly longer OS (HR: 0.83, 95.0% CI: 0.80–0.86). The survival benefit of aspirin use was maintained after propensity score matching at a ratio of 1:1 (HR: 0.79, 95.0% CI: 0.75–0.83)Back to article page
