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
objectivesAs transcatheter aortic valve replacement (TAVR) expands to lower-risk populations, understanding contemporary patterns of complications requiring surgical intervention remains critical. This study examines the incidence, predictors, and outcomes of major TAVR complications.
methodsThe National Inpatient Sample (2016-2021) was queried to identify adult patients undergoing TAVR. Major complications were defined as surgical aortic valve replacement, coronary artery bypass grafting, aortic intervention, pericardial drainage, VA-ECMO, cardiac repair, or diagnosis of aortic dissection/rupture. Multivariable logistic regression identified predictors of complications and failure-to-rescue.
resultsAmong 383 395 TAVRs, 4685 (1.2%) experienced major complications. Overall in-hospital mortality was 1.3%. Mortality was 26.0% in patients with major complications versus 1.0% without (P < .001). Stroke rates were also higher in patients with major complications (7.5% versus 1.8%, P < .001). Complications were associated with longer length of stay (8 vs 2 days) and higher hospital costs ($79,302 vs $45,469). Independent predictors of complications included age <65 (OR 2.27), bicuspid aortic valve (OR 1.79), thoracic aortic aneurysm (OR 1.49) and female sex (OR 1.24), while elective admission was protective (OR 0.51). Among patients with complications, VA-ECMO cannulation (OR 10.36), cardiac chamber repair (OR 3.14), and aortic dissection/rupture (OR 1.68) were strongest predictors of mortality.
conclusionsWhile the proportion of TAVR patients experiencing surgical emergencies has remained stable over time, the overall prevalence is increasing with the growth of TAVR, and these complications are associated with an in-hospital mortality rate of greater than 25%. Younger age, female sex, bicuspid valve, and thoracic aneurysm are associated with increased risk of major complications.
