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
backgroundEducation has been a well-established indicator of health. Against the background of educational expansion, little is known on how the temporal rise in educational attainment is affecting health trends. This study mainly examines the mediation effect of educational expansion on the trends of limitations in daily activity as measured by the global activity limitation indicator (GALI).
methodsThe study utilized data from the German Health Update survey (GEDA) using five waves between 2008 and 2024. Predicted probabilities and trends of (severe) limitation in daily activities were estimated using logistic regression analyses. Educational inequalities in the rates of limitation in daily activities in the five waves as well as their development over time were examined using the slope and relative indices of inequalities (SII, RII). Causal mediation analyses were applied to examine how educational expansion influenced the temporal development of (severe) limitations. All analyses were stratified by gender and three age groups.
resultsThe results reveal significant disparities in severe limitations in daily activities, particularly widening among the middle-aged group. The findings show divergent trends in limitation across age groups: older individuals have experienced considerable improvements, while younger individuals have experienced an increase in severe limitations over time. In both cases, educational expansion was found to have a positive mediating effect on the temporal development of (severe) limitations, reducing the exacerbation in younger individuals and contributing to the improvement in older individuals.
conclusionEducational expansion appears to have a positive influence on health trends, which reinforces the need for continued educational reforms. More focus is needed on younger individuals to explore factors behind their declining health. Additionally, addressing widening educational inequalities, particularly among middle-aged adults, is crucial for narrowing the gap between educational groups. Social challenges and the digital divide could be important contextual factors to address this development.
