Extended venous thromboembolism prophylaxis after bariatric surgery: the potential role of aspirin.
Article in Annals of medicine and surgery (2012), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Extended venous thromboembolism (VTE) prophylaxis after bariatric surgery remains an unresolved clinical issue. Current guidelines acknowledge the persistence of thrombotic risk beyond hospital discharge but do not define a standardized duration of pharmacological prophylaxis. In this perspective, a sequential strategy consisting of perioperative low-molecular-weight heparin followed by post-discharge aspirin is presented as a biologically plausible and pragmatically testable strategy for extended VTE prophylaxis in selected higher-risk bariatric patients. Persistent postoperative platelet hyperreactivity may contribute to sustained thrombotic risk after hospital discharge, providing a mechanistic basis for antiplatelet therapy during the extended prophylaxis phase. Although evidence supporting aspirin in this setting remains indirect, its oral administration, potential effects on platelet-mediated thrombosis, and favorable adherence profile support its evaluation as a hypothesis-generating strategy in this population.
