Less air pollution previously related to clean air and climate policies is linked to improved cognitive scores over time in NYC children.

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
backgroundPrenatal and postnatal exposure to air pollution has been associated in multiple epidemiological studies with adverse neurodevelopmental outcomes in children, including in New York City cohorts. Studies are lacking on changes in associations between air quality and neurodevelopmental outcomes over recent decades that have been marked by improvement in air quality. Here we investigated whether decreased prenatal exposure to air pollution, previously linked to clean air and climate policies in New York City, benefited cognitive development in children participating in cohort studies of the Columbia Center for Children's Environmental Health between 1998 and 2020. Information from such studies can benefit public health policy.
methodsWe utilized data on prenatal exposure to fine particulate matter (PM2.5), nitrogen dioxide (NO

conclusionsThese results indicate that, during the period of the largest reduction in air pollution levels, previously associated with air pollution and climate policies enacted in NYC, children's scores on cognitive tests improved, providing new evidence that such policies are beneficial to children's neurodevelopment.
