Prevalence and Prognostic Significance of Malnutrition Risk in Patients With Valvular Heart Disease.
Article in JACC. Advances, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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: Previous studies on the prevalence and prognosis of nutritional status in valvular heart disease (VHD) were primarily limited to aortic stenosis. The nutritional status of other types of VHDs remained an underexplored area. Objectives: This study aimed to evaluate the prevalence of malnutrition risk in different types of VHD and investigate the association between malnutrition risk and adverse clinical events. Methods: A total of 8,908 patients with moderate or severe VHD in the China-VHD Study underwent echocardiography and malnutrition risk assessment using the geriatric nutritional risk index (GNRI). The primary outcome was 2-year all-cause mortality, while the secondary outcome was 2-year major adverse cardiovascular events (MACEs). Results: Among 8,908 patients (mean age 61.8 ± 13.4 years; 56% male), approximately half were at risk for malnutrition. Patients with moderate or severe malnutrition risk had significantly higher risks of all-cause death and MACEs in various VHDs than those without malnutrition risk (all Conclusions: Malnutrition risk was prevalent in various VHDs and was strongly associated with increased mortality and MACEs. The GNRI score provided incremental prognostic information for clinical outcomes. Future research is needed to evaluate the impact of nutritional interventions on outcomes in these vulnerable patients.
