Kaplan-Meier analysis showing freedom from ischemic stroke in LAA closure group versus no LAA closure group.A, The survival curves show a significant difference in freedom from stroke in the group with LAA closure versus the group without LAA closure. B, Propensity score-adjusted Kaplan-Meier survival curves based on proportional hazard assumptions for patients who had LAA closure and those who did not have LAA closure show no significant difference in cumulative incidence of stroke between the 2 groups. LAA indicates left atrial appendage.
