Prenatal lead exposure modifies the association of maternal self-esteem with child adaptive ability.

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
backgroundA child's adaptive ability is important for personal career and social development. Maternal self-esteem may help shape a child's behavior. This study aims to investigate whether maternal self-esteem measured when their children were toddlers predicts their children's adaptive skills at school age, and whether prenatal lead exposure modifies such a relationship.
methodsWe assessed prenatal lead exposure using cord blood lead and maternal bone lead around delivery (tibia and patella lead measured in vivo by K-x-ray-fluorescence) among 192 mother-child pairs investigated in Mexico from 1994 to 2011. Maternal self-esteem was measured using the Coopersmith-Self-esteem-Inventory when children were 2 years old. When children were 7-to-15 years old, we measured children's blood lead levels and administered the 2nd edition of Behavior-Assessment-System-for-Children (BASC-2) parent-rating-scales (PRS) and Self-Reports of Personality (SRP) to evaluate children's adaptive skills.
resultsMedian (P25, P75) values for maternal patella and tibia lead, cord blood lead and children's current blood lead levels were 12.6 (3.2, 21.7) μg/g, 10.2 (4.1, 16.0) μg/g, 5.5 (3.5, 8.1) μg/dL and 2.7 (2.0, 4.0) μg/dL, respectively. In adjusted models, increased maternal self-esteem was associated with increased adaptive T-scores on the BASC-2 PRS and SRP scales. This relationship was weaker in high prenatal lead-exposure groups (high cord blood lead or patella lead groups, P25P100) compared with low prenatal lead-exposure (low cord blood lead or patella lead groups, P1P25) groups (P-interaction values < 0.10). No significant interactions between maternal tibia lead and self-esteem on children's adaptive T-scores were observed (P-interaction values > 0.10).
conclusionsToddlers of mothers with high (vs. low) self-esteem have better adaptive abilities when they are of school-age. Prenatal lead exposure may attenuate or eliminate this positive association.
