Restricted mean survival time of older adults with severe aortic stenosis referred for transcatheter aortic valve replacement.

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
backgroundFew studies have measured frailty as a potential reason for foregoing transcatheter aortic valve replacement (TAVR) in older adults with severe aortic stenosis (AS). This study sought to determine the impact of frailty and other clinician-cited reasons on restricted mean survival time (RMST).
methodsAn analysis of the McGill Frailty Registry was conducted between 2014 and 2018 at the McGill University Health Center Structural Valve Clinic. Consecutive nonsurgical patients referred for TAVR were included. In those that underwent balloon aortic valvuloplasty or medical management, the primary clinician-cited reason for foregoing TAVR was codified. Vital status was ascertained at 1 year and analysed using RMST and Kaplan-Meier analyses.
resultsThe study consisted of 373 patients with a mean age of 82.4 years, of which 233 underwent TAVR and 140 did not. Patients who did not undergo TAVR were more likely to be nonagenarians, with left ventricular dysfunction, chronic kidney disease, dementia, disability, depression, malnutrition, and frailty. The primary clinician-cited reason was: comorbidity in 34%, frailty in 23%, procedural feasibility and risks in 16%, and mild or unrelated symptoms in 27%. Compared to the TAVR group, 1-year RMST was reduced by 2.0 months in the medical management group (95% CI 1.2, 2.7) and by 1.1 months in the valvuloplasty group (95% CI -0.2, 2.5).
conclusionsPatients with severe AS referred for TAVR may never undergo the procedure on the basis of comorbidity, frailty, procedural issues, and symptoms. The best treatment decision is one that follows from multi-disciplinary assessment encompassing frailty.
