The association between AI use and other cardiac events (dysrhythmia, valvular dysfunction, and pericarditis) and heart failure/cardiomyopathy were unexpected and require further study. Multivariate Cox proportional hazards models using time-dependent endocrine drug use variables and propensity scores were conducted. O, Zucker It works by decreasing the amount of estrogen hormone your body makes, which slows or stops breast cancer cells from spreading or growing. J, Chetver Hazard ratios (HRs) and 95% CIs were estimated using Cox proportional hazards models with time-dependent medication use variables as described above; these models were adjusted for the aforementioned covariates.
