Diagnosis and Embolization of Pulmonary Esophageal Artery Hemoptysis in Lower Lobe Pulmonary Disease: Single-Center Study.

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
PurposeTo systematically evaluate PEA's contribution to lower lobe hemoptysis, characterize associated systemic-to-pulmonary shunts (SPS), and assess the safety/efficacy of polyvinyl alcohol (PVA) particle embolization.Materials and MethodsThis retrospective cohort study analyzed 428 patients with PEA-related hemoptysis (19% of 2296 TAE cases) treated at the First Affiliated Hospital of Guangzhou Medical University (2014-2023). Digital subtraction angiography (DSA) mapped PEA anatomy and SPS, followed by tailored PVA embolization (90-1000 μm). Outcomes included technical success, recurrence rates, and complications. Sex-disaggregated and etiology-disaggregated analyses were performed.Results99.1% (424/428) of PEA-associated lesions localized to lower lobes, predominantly left-sided (43.5%). Immediate hemostasis achieved in 95%, 1-month recurrence rate 5.1% (22/428). Multivariate Cox regression identified predictors: massive hemoptysis (HR = 2.03), ectopic bronchial arteries (HR = 1.54), thrombocytosis (>215 × 10
