One thousand five hundred fifty\u2010two patients were identified as nonstatin users and 4166 as statin users. The primary outcome of interest was the composite of cerebrovascular (transient ischemic attack, and fatal or nonfatal stroke) or cardiovascular events (fatal or nonfatal myocardial infarction). Time\u2010dependent Cox proportional hazard analyses were performed.

After adjusting for age, sex, prior history of stroke\/transient ischemic attack or myocardial infarction, diabetes mellitus, dyslipidemia, atrial fibrillation, chronic kidney disease, heart failure, and hypertension, statin use postradiotherapy was associated with a nonsignificant 15% relative risk reduction, but a strong trend toward reducing the primary outcome (hazard ratio=0.85 95%\n                      <jats:styled-content style=\"fixed-case\">CI<\/jats:styled-content>\n                      0.69\u20131.04,\n                      <jats:italic>P<\/jats:italic>\n                      =0.0811).
