Efficacy and safety of aspirin in preventing venous thromboembolism after hip arthroplasty for femoral neck fracture: a noninferiority prospective cohort study.
Observational study in BMC musculoskeletal disorders, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundVenous thromboembolism (VTE) is a common complication after hip arthroplasty. Here, we investigated the clinical efficacy and safety of prophylactic aspirin vs. conventional therapy in hip arthroplasty for femoral neck fracture.
methodsPatients who underwent total hip arthroplasty and hemiarthroplasty for femoral neck fractures between April 2021 and April 2024 were prospectively enrolled. Group A received oral aspirin (100 mg, once daily) as VTE prophylaxis; Group LR received low-molecular-weight heparin (4,250 U, once daily) sequentially followed by rivaroxaban (10 mg, once daily). The patients were followed up for 90 days postoperatively. Safety and efficacy were comprehensively evaluated based on postoperative VTE incidence, laboratory blood tests, bleeding events, and other complications.
resultsGroup A was noninferior to Group LR in preventing VTE (incidence rates of 11.6% and 10.1%, respectively, with a rate difference of 1.5%, 95% CI: 0.7-2.3%, P for non-inferiority test = 0.017). There was no significant difference between the groups in the incidence of bleeding events (3.3 vs. 8.4%; P = 0.092). Furthermore, the rates of other complications did not differ significantly between groups.
conclusionIn patients undergoing hip arthroplasty for femoral neck fractures, the efficacy and safety of oral aspirin for preventing VTE was similar to that of low-molecular-weight heparin followed by rivaroxaban.
