Impact of Preoperative Malnutrition and Sarcopenia on Clinical Outcomes After 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
Background: The impact of coexisting malnutrition and sarcopenia on survival after transcatheter aortic valve replacement (TAVR) has not been fully studied. Methods and Results: Among 513 consecutive patients undergoing TAVR between February 2014 and June 2023, 340 with available preoperative Geriatric after Nutritional Risk Index (GNRI) and Short Physical Performance Battery (SPPB) data were categorized into 4 groups based on malnutrition (GNRI <98) and sarcopenia (SPPB ≤9) status: malnutrition and sarcopenia (N=98); malnutrition without sarcopenia (N=69); no malnutrition with sarcopenia (N=83); neither malnutrition nor sarcopenia (N=90, reference). The primary outcome measure was all-cause death. Patients with both malnutrition and sarcopenia were older and had a higher prevalence of anemia compared with the reference group. The cumulative 5-year mortality rate was significantly higher in this group. After adjusting for confounders, coexistence of malnutrition and sarcopenia had a significantly higher risk for all-cause death (hazard ratio [HR] 3.15; 95% confidence interval [CI]: 1.68-5.89; P<0.001). In contrast, malnutrition without sarcopenia (HR 1.36; 95% CI 0.64-2.90; P=0.42) and no malnutrition with sarcopenia (HR 1.86; 95% CI 0.92-3.79; P=0.08) were not associated with increased mortality. Conclusions: The coexistence of malnutrition and sarcopenia significantly increased mortality risk after TAVR, which highlights the importance of integrating both nutritional and sarcopenia assessments into preoperative risk stratification to optimize outcomes in patients undergoing TAVR.
