Comprehensive assessment of sarcopenia in patients with severe aortic stenosis undergoing transcatheter valve implantation.

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
Background: Transcatheter aortic valve implantation (TAVI) is an effective treatment for aortic stenosis (AS), particularly in older, frail and sarcopenic patients. This study aimed to assess the prevalence of sarcopenia in patients undergoing TAVI and evaluate its imaging and functional markers. Methods: This prospective single-center study included consecutive patients aged ≥ 75 years undergoing TAVI for symptomatic severe AS. Sarcopenia was assessed per the 2018 European Working Group on Sarcopenia in Older People 2 criteria, including muscle strength (hand grip, chair stand), muscle quantity (computed tomography, bioelectrical impedance, ultrasound), and physical performance (Short Physical Performance Battery, Timed Up and Go, 5-Meter and 6-Minute Walk). Results: Thirty patients (83.2 ± 16 years) with severe aortic stenosis (AVA 0.79 cm Conclusions: Sarcopenia is highly prevalent among patients undergoing TAVI. Body composition parameters derived from bioimpedance strongly correlate with computed tomography measurements. There is a need for a simplified diagnostic approach to sarcopenia in AS patients.
