Transcatheter aortic valve implantation-related futility: prevalence, predictors, and clinical risk model.
Observational study in Heart and vessels, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Futility denotes failure to achieve the projected outcome. We investigated the prevalence, predictors, and clinical risk model of transcatheter aortic valve implantation (TAVI)-related futility. We included 464 consecutive patients undergoing TAVI from 2010 to 2017. Futility was defined as death and/or hospitalization for heart failure (HFH) within 1 year after TAVI. Of 464 patients (mean age: 84.4 years), 69% were females (EuroSCOREII: 6.3%; Society of Thoracic Surgeons [STS] score: 6.9%). Forty-six patients (9.9%) experienced TAVI-related futility, and 36 of 46 patients (69.6%) died within 1 year due to cardiac (37.5%) and non-cardiac (62.5%) causes. Previous HFH (hazard ratio [HR], 2.20; 95% confidence interval [CI]: 1.13-4.35, p = 0.020), chronic obstructive pulmonary disease (COPD) (HR, 3.39; 95% CI: 1.12-8.42, p = 0.033), and moderate/severe mitral or tricuspid regurgitation (HR, 2.98; 95% CI: 1.32-6.27, p = 0.010) were independent predictors of futility. With 1 point assigned to each predictor (total 0 point, futility low-risk; total 1 point, futility intermediate-risk; total 2-3 points, futility high-risk), the futility risk model clearly stratified individual futility risk into three groups (the freedom from futility at 1 year: 96.2%, 82.1%, and 67.9% each). Our futility risk model presented better discrimination than EuroSCOREII, and STS score (c-statistic: 0.73 vs. 0.68 vs. 0.67). Medical futility was recognized in 9.9% of patients undergoing TAVI. Previous HFH, COPD, and concomitant atrioventricular regurgitation were associated with futility. The risk model derived from three predictors showed good performance in predicting futility risk.
