Causal effect of mandatory elementary education textbooks on literacy and cognition of low socioeconomic status older adults.
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. 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
backgroundPrevious research has suggested that early-life education can help build cognitive reserve, providing resilience against late-life cognitive decline. The research on education and late-life cognitive health, however, has focused more on developed nations and higher levels of education. This research examines the effects of an elementary school policy on literacy, education, and late-life cognitive health.
methodsWe analyzed, through a shift-share instrumental variable approach, the causal effect on late-life cognitive health of an exogenous policy change that introduced free and mandatory textbooks in 1960 for elementary schools in Mexico. This change essentially made elementary school attendance universal. For our analysis, we used the Mexican Health and Aging Study (MHAS) and Census datasets linked to 1960 literacy rates for cohorts born between 1930 and 1965. The MHAS and Censuses include data on literacy and early-life education. The MHAS additionally includes data on late-life cognitive engagement and functioning.
resultsWe found that the textbook program increased literacy, years of education, and late-life cognitive engagement. We found improvements in cognition for those with lower early-life socioeconomic status.
conclusionsThere is scarce literature analyzing the causal effect of literacy and early-life education policies in developing countries on late-life cognitive engagement and functioning. Our results, particularly for the most vulnerable populations, suggest that elementary educational policies in low- and middle-income countries can boost cognitive engagement and function in late life.
