Does additional education affect memory consistently? An analysis of compulsory schooling reforms across Europe and U.S.
Article in Social science & medicine (1982), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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
backgroundA growing literature suggests that education positively influences cognitive function in later life. However, the magnitude and consistency of this effect across study designs and populations remain open questions.
methodsThis study re-examines results from the quasi-experimental studies of compulsory schooling reforms in Europe and the United States that estimate the causal effect of education on late-life memory performance. We use harmonized aging survey data from a new systematic coding and documentation of compulsory schooling laws (the Gateway to Global Aging's Education Policy Explorer), and estimate the robustness of findings across a set of methodological decisions (regression specifications, and sample restrictions).
resultsLarge sample size requirements often lead to underpowered studies, and researchers face numerous degrees of freedom in their statistical specification, including subpopulation definitions, choice of outcome variables, and functional forms. While most published studies report positive effects of education on memory, we find that the results of the cross-country continental European studies are not robust to specification choices. Results for the UK and US reforms are more robust to specification choices.
conclusionOur findings highlight the importance of comparability and assessment of robustness to alternative regression specification choices when estimating effects of compulsory schooling on memory.
