The Long Arm of Childhood Policy: Historical Schooling Laws and COVID-19 Pandemic-era Mortality.
Article in Epidemiology (Cambridge, Mass.), 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
backgroundLow educational attainment was strongly associated with higher coronavirus disease 2019 (COVID-19) mortality. Whether this association is causal remains controversial. We evaluated the impact of historical state-level compulsory schooling laws (CSLs) on older individuals' pandemic-era mortality via a natural experiment.
methodsWe defined the US population of older adults using the 2019 American Community Survey and included all US death certificates from March 2019 to December 2021. We linked each individual to state-level CSLs at school age. We estimated effects of state-level CSLs on individual-level COVID-19 mortality and all-cause mortality pre-pandemic (March 2019-February 2020), pandemic year 1 (March 2020-February 2021), and pandemic year 2 (March 2021-December 2021), controlling for birth year, sex, race and ethnicity, state-level demographics, and state-of-birth fixed effects. We also examined the effect heterogeneity by sex and racial identity.
resultsEach additional year of policy-mandated compulsory schooling was associated with lower odds of COVID-19 mortality (pandemic year 1 odds ratio [OR] for 8 vs. 9 years: 1.16 [95% confidence interval [CI]: 1.11, 1.20]; OR for 10 vs. 9 years 0.96 [95% CI: 0.93, 0.98]; similar estimates in year 2). The relationship between CSLs and COVID-19 mortality roughly mirrored the relationship with all-cause mortality immediately before and during the pandemic. The gradient was steepest among Black women.
conclusionOlder adults born into states requiring longer schooling experienced markedly lower mortality during the pandemic, suggesting historic investments in children's education reduced pandemic-era mortality decades later. Our findings support a causal relationship between population-level education policy and long-term population health.
