Prenatal Environmental Antibiotic Exposure and Autism Spectrum Disorder Symptoms in Children at 3 Years of Age: Findings from the Ma'anshan Birth Cohort Study.
Article in Environment & health (Washington, D.C.), 2024. 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
Antibiotic exposure during pregnancy may affect the neurodevelopment of children, but biomonitoring-based population studies on this class of new pollutants are lacking. We conducted a prospective birth cohort study of 2860 mother-child pairs, measured the urinary concentrations of 41 antibiotics and their two metabolites over three trimesters, and assessed children's autism spectrum disorder (ASD) symptoms at 3 years of age. We examined the associations between prenatal antibiotic exposure and children's ASD symptoms. The least absolute shrinkage and selection operator regression screened for Tetracycline and Ofloxacin as important predictors of ASD symptoms. Modified Poisson regression models revealed that maternal Tetracycline exposure throughout pregnancy increased the risk of ASD symptoms (RR: 1.66, 95% CI: 1.14, 2.40). Maternal Tetracycline exposure during the first (RR: 1.74, 95% CI: 1.13, 2.68) and third trimesters (RR: 1.86, 95% CI: 1.16, 3.00) increased the risk of ASD symptoms in boys, and Ofloxacin exposure during the first trimester (RR: 1.47, 95% CI: 1.07, 2.02) increased the risk of ASD symptoms in girls. No dose-dependent relationships between prenatal antibiotic exposure and ASD symptoms were validated by restricted cubic splines. Prenatal exposure to Tetracycline and Ofloxacin may increase the risk of ASD symptoms in children, and the first and third trimesters might be the key windows.
