Exposure to Chinese famine in early life and the risk of multimorbidity in adulthood.
Article in BMC public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectivesPrevious studies had reported the association between famine exposure in early life and subsequent non-communicable diseases risk. In current study, we aimed to evaluate the associations between famine exposure on multimorbidity prevalence and incidence in middle-aged and older Chinese population.
methodsA total of 13,254 participants from the China Health and Retirement Longitudinal Study 2011 were included in cross-sectional analyses. 5,780 participants were including in longitudinal analyses and were followed up in 2020. Based on the questionnaire, participants were divided into non-exposed, mild famine, moderate famine and severe famine subgroups.
resultsIn cross-sectional analyses, both mild, moderate and severe famine groups were significantly associated with higher multimorbidity prevalence. During the 9 years of follow-up, a total of 2,643(45.73%) participants with multimorbidity incident were identified. After adjusting for all covariates, individuals who experienced mild famine, moderate famine and severe famine were significantly associated with increased risk of multimorbidity incident, with the corresponding ORs (95%CI) being 1.32(1.14-1.52), 1.54(1.21-1.96) and 1.62(1.32-1.99), respectively. DISCUSSION: Our findings indicate that famine exposure in mild, moderate and severe famine groups might be associated with an increased multimorbidity risk.
