Safety of apixaban and rivaroxaban compared to warfarin after cardiac surgery.
Trial report in Journal of cardiac surgery, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundDirect oral anticoagulants (DOACs) are frequently prescribed for the management of atrial fibrillation and venous thrombosis. There is a lack of published data on the utilization of DOACs in individuals who have undergone recent cardiac surgery. The purpose of this study was to evaluate the safety and efficacy of apixaban and rivaroxaban compared to warfarin in patients postcardiac surgery.
methodsIn this retrospective cohort study, patients were separated into a DOAC cohort or a warfarin cohort based on the agent they received after cardiac surgery. Patients could be included if they were ≥18 years of age and received or were discharged on either rivaroxaban, apixaban, or warfarin within 7 days after cardiac surgery. The primary outcome for the study was the rate of International Society on Thrombosis and Hemostasis (ISTH) major bleeding during hospitalization and for 30 days following discharge or until first follow-up appointment.
resultsThere were a total of 194 patients included in the analysis, 97 in the DOAC cohort and 97 in the warfarin cohort. Four patients (4.1%) in the DOAC group experienced ISTH major bleeding, while 2 patients (2.1%) in the warfarin cohort experienced ISTH major bleeding (p = 0.68). No patients in the DOAC cohort experienced a thrombotic event, whereas 2 patients (2.1%) in the warfarin cohort experienced a thrombotic complication (p = 0.5).
conclusionApixaban and rivaroxaban demonstrated similar safety when compared to a matched cohort of warfarin patients. Larger prospective randomized studies are needed to confirm these findings.
