Prenatal sugar exposure shapes late-life human capital and health.
Article in PNAS nexus, 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
Maternal sugar consumption during pregnancy may have a variety of effects on offspring. We exploit the abolishment of the rationing of sweet confectionery in the United Kingdom on 1949 April 24, and its subsequent reintroduction some months later, in an era of otherwise uninterrupted rationing of confectionery (1942-1953), sugar (1940-1953), and many other foods, and we consider effects on late-life cardiovascular disease, body mass index (BMI), height, type-2 diabetes, and the intake of sugar, fat, and carbohydrates, as well as cognitive outcomes and birth weight. We use individual-level data from the UK Biobank for cohorts born between April 1947 and May 1952. We also explore whether one's genetic "predisposition" to the outcome can moderate the effects of prenatal sugar exposure. We find that prenatal exposure to derationing increases education and reduces BMI and sugar consumption at higher ages, in line with the "developmental origins" explanatory framework, and that the sugar effects are stronger for those who are genetically "predisposed" to sugar consumption.
