Cognitive maintenance in older adults in social classes: a secondary analysis of the longitudinal SHARE data.
Article in Journal of epidemiology and community 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
backgroundCognitive maintenance-defined as a capacity to maintain good or excellent cognitive functioning-is a valuable ageing outcome. Socio-demographic, dementia risk and protective factors may contribute differently to it across social classes. However, these effects have not been adequately assessed yet.
objectiveThis study aims to evaluate the effects of socio-demographic, risks and protective factors on the probability of cognitive maintenance in older adults stratified by social classes.
methodsParticipants aged 65-85 years at the baseline from the Survey on Health, Ageing and Retirement in Europe (Waves 5 (2013) and 7 (2017)) were included. Cognitive maintenance was operationalised as six or more words recalled on the 10-word delayed recall test at baseline and follow-up. Dementia-specific risks and protective factors were selected from global strategies for dementia prevention. Multilevel logistic regressions with the country of residence as a random-effect variable were constructed to compare the relative effect of contributors across social classes.
results20 960 participants from 14 countries were included in the analysis. The pseudo-R
conclusionStudying contributors to cognitive maintenance separately in social classes may show possible targets of public health strategies for improving cognitive health in populations and reducing social inequalities in cognitive health.
