Pharmacological thromboprophylaxis in hospitalized patients with acute infectious diseases: a meta-analysis.
Synthesis in European journal of clinical pharmacology, 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
introductionVenous thromboembolism (VTE) may be a significant complication in medical patients, and infectious disease has been highlighted as an additional risk factor. Pharmacological thromboprophylaxis can prevent VTE and is recommended in at-risk populations, but not routinely in patients with infectious diseases.
methodsWe conducted a systematic review and meta-analysis of studies on the effectiveness of pharmacological thromboprophylaxis in patients with acute infections, excluding those involving COVID-19. The primary outcome was VTE events. Secondary outcomes were mortality and adverse events related to anticoagulant therapy.
resultsData from seven studies (four randomized controlled trials and three observational studies) involving 16,994 patients with infectious diseases were analyzed. Pharmacological thromboprophylaxis regimens consisted of unfractionated heparin, low-molecular-weight heparin (enoxaparin or dalteparin), and fondaparinux. The severity of the disease varied from acute infections to sepsis. Six studies reported fewer VTE events with thromboprophylaxis. The meta-analysis yielded a pooled odds ratio of 0.50 [95% CI: 0.37-0.69, I
conclusionThis analysis quantifies the effect of thromboprophylaxis in patients with acute infectious diseases. Although available results show that thromboprophylaxis is associated with fewer VTE events, limited data, sparse safety and mortality reporting, and heterogeneity among studies preclude reliable risk-benefit evaluation. Further prospective research is warranted.
