Repeated Gastrointestinal Disease Reporting and Subsequent Multidomain Health Deterioration: Longitudinal Analyses in CHARLS and ELSA.
Article in Geriatrics & gerontology international, 2026. 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
aimTo examine whether repeated gastrointestinal disease reporting was associated with subsequent multidomain health deterioration and whether the direction of association was consistent across two national aging cohorts.
methodsCHARLS was the primary longitudinal cohort. Participants with at least two gastrointestinal exposure assessments across waves 1-3 were classified as never, intermittent/low, or persistent/high reporting. The primary composite comprised cognitive, ADL, IADL, or depressive-symptom deterioration. Logistic and robust Poisson models were fitted. ELSA provided a cross-cohort consistency analysis using a pre-Wave-1 gastrointestinal disease/medication proxy.
resultsCHARLS included 12 144 participants/5607 events; fully adjusted models included 9555/4523. Adjusted relative risks were 1.10 (95% CI 1.03-1.18) for intermittent/low and 1.06 (1.01-1.11) for persistent/high reporting. In ELSA, the fully adjusted three-level education model included 3286/1752 and yielded an odds ratio of 1.24 (0.97-1.59); the longitudinal-weighted estimate was 1.21 (0.90-1.63). Gastrointestinal exposure produced negligible incremental discrimination in either cohort.
conclusionsRepeated gastrointestinal reporting was associated with a small increase in subsequent deterioration in CHARLS, while ELSA estimates were directionally similar but less precise. Gastrointestinal history may prompt broader geriatric assessment but is not a stand-alone predictor or evidence of causality.
