Dentin Metal and Trace Elements in Deciduous Teeth: Findings from Project Viva.
Article in Environmental science & technology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Deciduous teeth can reveal historical exposure to metals, yet their distribution within populations remains underexplored. This study aimed to characterize metal levels in deciduous teeth, compare measurements across duplicate teeth, and assess associations with maternal blood metal concentrations during pregnancy, while considering maternal and child characteristics. We recruited women into Project Viva between 1999 and 2002 during early pregnancy. During follow-up study visits between 2017 and 2020, the women provided their child's deciduous teeth. Dentin metal concentrations were analyzed using laser ablation-inductively coupled plasma-mass spectrometry, covering a measurement range from 21 weeks before to 55 weeks after birth. Multiple teeth were compared using Bland-Altman plots and cross-correlations. Maternal erythrocyte metals were measured in the first and second trimesters using ICP-MS. Significant positive correlations were found between maternal erythrocyte Pb and child's dentin Pb, particularly with the strongest association observed between second trimester maternal Pb and prenatal dentin Pb (Spearman
