Researchers used real-world clinical data to attempt to emulate a randomized controlled trial testing the effectiveness of two blood thinners, apixaban and warfarin, to prevent stroke in patients with non-valvular atrial fibrillation. The study provides a method to explore the effects of treatments in patients who are underrepresented or excluded from clinical trials.
