Aspirin as a thromboprophylaxis agent after revision knee arthroplasty: A retrospective analysis.

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
Introduction: Total knee arthroplasty is a common and effective procedure. Although complication rates are low, certain complications such as venous thromboembolism are potentially serious. The optimal prophylactic agent and dosage after revision knee arthroplasty remains unclear. The main objective of this work was to study the efficacy and safety of aspirin as a thromboprophylaxis agent following revision knee arthroplasties. Patients and methods: A retrospective review of patients undergoing revision knee arthroplasty between 2013 and 2020at a University Teaching Hospital was undertaken. The primary outcome was the development of a symptomatic thromboembolic event requiring treatment within 90 days post-surgery. The secondary outcomes were adverse events associated with aspirin therapy: surgical site infection rate; incidence of major bleeding; readmission rate and mortality within 90 days post-surgery. Results: 490 patients were included. 374 (76.3%) received prophylactic aspirin (150 mg once daily for 28 days) and 75 (15.3%) patients received dalteparin for 28 days due to contraindication to aspirin use. Those already receiving other thromboprophylaxis agents for pre-existing comorbidities continued these after relevant medical consultation. The overall rates of venous thromboembolism and symptomatic DVT after aspirin prophylaxis were 0.6% (3/490) and 0.8% (3/374), respectively. VTE incidence did not significantly differ between those administered aspirin and other agents. No patient experienced major bleeding within 90 postoperative days. Only 2 of 490 (0.4%) patients had wound infection requiring readmission; neither received prophylactic aspirin. Conclusion: Extended out-of-hospital thromboembolic prophylaxis with aspirin may be at least as effective as other agents in patients undergoing revision knee arthroplasty. Aspirin is safe, effective, and cheap compared with other agents.
