1 · What the graph read from it

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.

2 · The registry

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

Background: Venous thromboembolism (VTE) is a frequent complication in malignancy. Low-molecular-weight heparins and direct oral anticoagulants have replaced vitamin K antagonists (VKAs) as the standard of care for cancer-associated VTE. Nonetheless, clinical trials have not established a survival benefit of these agents compared with VKA. Objectives: We conducted a systematic review and meta-analysis to compare survival in cancer patients receiving VKA vs other anticoagulants. Methods: We searched Embase, Web of Science, PubMed, ClinicalTrials.gov, and Cochrane from inception until April 10, 2025, focusing on the use of VKA and non-VKA in cancer patients. Primary outcome was mortality and secondary outcomes included thromboembolism and bleeding. Results: Of 11,198 studies screened, 14 studies (70,025 patients) were included. VKA were associated with lower mortality than non-VKA in observational studies (odds ratio [OR], 0.84; 95% CI, 0.78-0.91; Conclusion: The use of VKA was associated with lower mortality than non-VKA anticoagulation in patients with cancer in observational studies but not in randomized trials. The analysis was limited by high heterogeneity, which must be considered when interpreting results.
