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
backgroundSocioeconomic status (SES) and family relationships are critical social determinants of health disparities. The mechanisms underlying their interactions remain insufficiently understood in Asian cultures with prevalent intergenerational cohabitation. This study investigates the independent and combined effects of SES and family relationships on all-cause mortality in China.
methodsA baseline survey was conducted in 2010 involving 9280 adult permanent residents from 12 counties (districts) in Guizhou Province, using stratified cluster random sampling. Two follow-ups (2016-2020, 2023) were conducted. SES was assessed using a composite score comprising household income, education, and occupation, while family relationships were classified as either "good" or "mediocre." The Cox proportional hazards model was employed to evaluate the independent and combined effects of SES and family relationships on all-cause mortality.
resultsAmong 5949 participants were included, and the cumulative mortality rate was 6.4% over a median follow-up of 12 years. With a decrease in mortality risk as SES increased (P < 0.001). Compared with SES ≤ 6, mortality risk with SES scores of 7, 8, and ≥ 9 decreased by 36.9% (HR = 0.631, 95% CI = 0.473-0.842), 36.6% (HR = 0.644, 95% CI = 0.469-0.886), and 73% (HR = 0.270, 95% CI = 0.183-0.397), respectively. The independent effect of family relationship on the risk of death was not statistically significant (HR = 0.847, 95% CI = 0.0.670- 1.070). The joint analysis showed the compensatory effect was significant when SES exceeded a threshold (SES ≥ 9), alleviating the mortality risk associated with family relationships (HR = 0.2197, 95% CI = 0.073-0.652).
conclusionFindings demonstrate SES independently reduces mortality in Chinese populations, while the effect of family relationships is modulated by cultural background. The resource substitution hypothesis is valid at specific SES thresholds. Intervention efforts should prioritize the vulnerable group characterized by "low SES and weak family support".
