Predictors of Recurrence Following Bronchial Artery Embolisation (BAE) for Haemoptysis: A Systematic Review and Evidence Synthesis Analyses Using SWiM Guidelines.
Review in Cardiovascular and interventional radiology, 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
purposeThis systematic review aims to identify independent etiological, anatomical, and procedural predictors of recurrent haemoptysis following Bronchial artery embolisation (BAE) using a Synthesis Without Meta-analysis (SWiM) framework. MATERIALS AND
methodsPubMed, Cochrane, and Scopus were systematically searched in February 2026 for cohort studies analysing post-BAE haemoptysis recurrence in line with PRISMA guidelines. Data were synthesised using a SWiM approach as clinical heterogeneity and intra-cohort mixing of embolic agents precluded a meta-analysis. Multivariable evidence was prioritised over univariable results to determine the independent direction-of-effect, using a SWiM vote-counting approach. GRADE framework was used to assess the certainty of evidence.
resultsSixty-five studies involving 12,143 patients met the inclusion criteria. Across multivariable evidence, systemic-pulmonary shunts, non-bronchial systemic collaterals (NBSCs), pleural thickening, bronchiectasis, aspergillosis, prior history of haemoptysis, positive sputum culture, and abnormal platelet indices were identified as positive independent predictors of recurrence. Conversely, active tuberculosis, pulmonary malignancy, post-tuberculous sequelae, high-volume haemoptysis, cystic fibrosis, and concurrent anticoagulant use were neutral predictors. Analysis of embolic agents did not demonstrate a clear superiority of any specific agent.
conclusionChronic parenchymal destruction and systemic-pulmonary shunts are primary factors in long-term BAE failure due to haemoptysis recurrence as compared to presentation characteristics or embolic agents. Thorough angiographic investigation for cryptic collaterals and post-procedural management of underlying diseases is important for the efficacy of BAE.
