Cardiology involvement (A) was less likely to occur among patients with history of cancer than those without (RR=0.92, 95% CI=0.91–0.93), and similar differences were observed for cancers of the colon, lung, pancreas, and hematologic system. Anticoagulant prescription fills (B) were less likely among patients with history of cancer than those without cancer (RR=0.89, 95%CI=0.88–0.90), and similar results were observed for cancers of the colon, lung, pancreas, prostate, and hematologic system. *P<0.05.
