Study design. The index date for nonusers in the matched set corresponded to the date of their incident atrial fibrillation (AF) diagnosis plus the time between their matched user’s incident AF diagnosis date and the warfarin prescription date.

Incidence (number of events and rates per 100 person-years) of study outcomes by warfarin use and estimated glomerular filtration rate (eGFR) category. (A) All-cause death, ischemic stroke, or transient ischemic attack (TIA); (B) ischemic stroke or TIA; (C) all-cause death; and (D) major bleeding. Bars represent 95% confidence intervals (per 100 person-years) for incidence rates.
