Sex-specific associations between maternal prenatal and postnatal psychological distress and autism spectrum disorder in the Japan Environment and Children's Study.
Article in Scientific reports, 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
Maternal prenatal and postnatal psychological distress, including depression and anxiety are risk factors for the development of autism spectrum disorder (ASD) in children. However, there is inconsistent knowledge regarding the period in pregnancy during which psychological distress may influence this risk, and the associated sex-specific differences. We evaluated the association between the six-item Kessler Psychological Distress Scale (K6) for mothers and ASD in 6-year-old children, using the Japan Environment and Children's Study dataset. In total, 32,417 boys and 30,996 girls were included in the analysis. The K6 was administered during the first half of pregnancy (medians of 15 weeks); the second half of pregnancy (medians of 27 weeks); and at 1 year postpartum, and multivariate logistic regression analyses were performed on the group with a K6 score ≤ 4 as reference. In boys, maternal psychological distress in the first half of pregnancy and at 1 year postpartum were associated with ASD. In girls, maternal psychological distress coexisting during pregnancy and at 1 year postpartum was associated with ASD.
