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
purposeVenous thromboembolism (VTE) is a significant postoperative complication. The most recommended prophylactic measures involve using the unfractionated heparin, and low molecular weight heparins. Since oral anticoagulants can be administered orally and are cost-effective, they have recently gained attention as a newer intervention. This study aimed to compare the effects of rivaroxaban, and enoxaparin thromboprophylaxis in degenerative spine surgeries.
methodPatients diagnosed with degenerative disc disease, and undergoing spinal surgery were randomly assigned to receive either a subcutaneous injection of 40 mg enoxaparin or 10 mg oral rivaroxaban daily in a non-inferiority trial. The evaluation at two weeks, and three months after surgery included the assessments of VTE and other postoperative complications.
resultAccording to the study protocol, 220 patients were enrolled in the study and included in the intention-to-treat analysis. However, the results were only available for 204 subjects as per-protocol. Ninety-seven in enoxaparin and 107 in rivaroxaban group. VTE was detected in 4 patients (3.6%) in the enoxaparin group, and 2 patients (1.9%) in the rivaroxaban group (P = 0.154). Reoperation rates were significantly higher in the enoxaparin group (P = 0.008). Moreover, the enoxaparin group experienced a significantly longer hospital stay (P = 0.033). However, other outcomes did not show significant differences between two groups (P > 0.05).
conclusionThis study shows that rivaroxaban effectively prevents VTE incidence in degenerative disc spinal surgeries which is non-inferior to enoxaparin in terms of VTE prophylaxis. Furthermore, the patients in the rivaroxaban group experienced shorter hospital stays and a lower necessity for reoperation.
