1 · What the graph read from it

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.

2 · The registry

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

purposeThe Sheyang Mini Birth Cohort Study (SMBCS) aimed to assess the impact of prenatal and postnatal environmental factors on children's development.

participantsSMBCS was established in Sheyang County, Jiangsu Province, China. Between June 2009 and January 2010, 1303 healthy pregnant women residing in Sheyang for at least 1 year were recruited along with their 1312 newborns. By 2025, the SMBCS had completed 11 follow-up rounds covering children ages 1-16, with a total of 4696 postnatal visits. Questionnaire interviews, physical examinations, neurodevelopmental and pubertal assessments and biological sample collection were conducted at each follow-up. A series of analytical methods were applied to determine contaminants including pesticides, phenols, polyfluoroalkyl substances, polybrominated diphenyl ethers, metals and metabolites in biological samples. FINDINGS TO DATE: SMBCS reported widespread exposure to multiple environmental contaminants, with exposure levels varying across developmental stages. Both individual and combined exposure effects were observed on physical, neural and pubertal development. Several studies have also identified potential metabolic, monoamine and hormonal pathways underlying these adverse health effects. FUTURE PLANS: The SMBCS will continue to pay attention to the impact of environmental pollutants on children's health. As children grow older and with the advancement of new technologies, the focus of SMBCS will shift from the early life health effects of long-term, low-dose environmental pollutant exposome on the health status and developmental outcomes during adolescence and adulthood.
