Prevalence and Intensity of Catastrophic Health Expenditure Among Residents in a Multiethnic Province in China: Cross-Sectional Study.

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
backgroundHainan is a pilot free trade port in China and a multiethnic province. Catastrophic health expenditure (CHE) reflects health care inequity, particularly affecting vulnerable groups in rapidly developing multiethnic regions.
objectiveThis study aims to analyze CHE prevalence and intensity and their influencing factors among residents in a Chinese multiethnic province.
methodsData from the 2023 Hainan Province Health Services Survey, conducted among 14,532 individuals aged 18 years or older, were used in a multistage stratified cluster sampling. CHE was defined as out-of-pocket health care payments exceeding 40% of the household's capacity to pay. The chi-square test and a logistic regression were used to identify influencing factors for CHE. Nonparametric tests and quantile regression were used to evaluate the influencing factors for CHE intensity.
resultsThe prevalence of CHE in Hainan province was 8.37%, with a median intensity of 17.67% (IQR 8.31%-29.77%). Residents were more likely to experience CHE if they were older than 60 years (odds ratio [OR] 1.928, 95% CI 1.602-2.320; P<.001), unmarried (OR 1.241, 95% CI 1.075-1.433; P=.003), or had chronic illnesses (OR 2.214, 95% CI 1.930-2.540; P<.001). Ethnic minority groups (OR 0.774, 95% CI 0.679-0.883; P<.001) as well as middle-income (OR 0.722, 95% CI 0.600-0.869; P=.001), high-middle-income (OR 0.739; 95% CI 0.609-0.898; P=.002), and high-income (OR 0.591, 95% CI 0.474-0.738; P<.001) groups were less likely to experience CHE. At lower CHE intensity (20th percentile), individuals older than 60 years (β=1.935; P=.03) and middle-income (β=1.737; P=.04) and rural (β=2.202; P=.005) residents showed positive associations. At the 50th percentile, low-middle-income (β=-5.052; P=.005), high-middle-income (β=-4.203; P=.03), and high-income (β=-6.534; P=.004) groups showed negative associations. At the 80th percentile, high-middle-income (β=-7.143; P=.03) and rural (β=-6.241; P=.005) groups showed stronger financial protection.
conclusionsAddressing CHE risks remains a critical challenge in Hainan province, highlighting structural inequities rooted in socioeconomic disparities and health vulnerabilities. Therefore, policy should prioritize primary prevention in the lowest-income populations while implementing enhanced insurance coverage for rural populations facing extreme costs to alleviate the most severe financial burdens.
