Characteristics, interventions and outcomes of patients with valvular heart disease hospitalised in China: a cross-sectional study.
Article in BMJ open, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
objectivesLittle is known about contemporary characteristics and management of valvular heart disease (VHD) in China. This study aimed to examine the clinical characteristics, aetiology and type of VHD, interventions and in-hospital outcomes of patients with VHD hospitalised in China.
methodsWe used a two-stage random sampling design to create a nationally representative sample of patients with VHD hospitalised in 2015 in China and included adult patients with mild, moderate or severe VHD. We abstracted data from medical records, including echocardiogram reports, on patient characteristics, aetiology, type and severity of VHD, interventions and in-hospital outcomes. We weighted our findings to estimate nationally representative hospitalisations. We performed multivariable logistic regression analysis to identify factors associated with valve intervention.
resultsIn 2015, 38 841 patients with VHD were hospitalised in 188 randomly sampled hospitals, representing 662 384 inpatients with VHD in China. We sampled 9363 patients, mean age 68.7 years (95% CI 42.2 to 95.2) and 46.8% (95% CI 45.8% to 47.8%) male, with an echocardiogram. Degenerative origin was the predominant aetiology overall (33.3%, 95% CI 32.3% to 34.3%), while rheumatic origin was the most frequent aetiology among patients with VHD as the primary diagnosis (37.4%, 95% CI 35.9% to 38.8%). Rheumatic origin was also the most common aetiology among patients with moderate or severe VHD (27.3%, 95% CI 25.6% to 29.0% and 33.6%, 95% CI 31.9% to 35.2%, respectively). The most common VHD was mitral regurgitation (79.1%, 95% CI 78.2% to 79.9%), followed by tricuspid regurgitation (77.4%, 95% CI 76.5% to 78.2%). Among patients with a primary diagnosis of severe VHD who were admitted to facilities capable of valve intervention, 35.6% (95% CI 33.1% to 38.1%) underwent valve intervention during the hospitalisation. The likelihood of intervention decreased significantly among patients with higher operative risk.
conclusionsAmong patients with VHD hospitalised in China, the predominant aetiology was degenerative in origin; among patients with moderate or severe VHD, rheumatic origin was the most common aetiology. Targeted strategies and policies should be promoted to address degenerative VHD. Patients with severe VHD may be undertreated, particularly those with high operative risk.
