Maternal exposure to oil spill and children's mental health: The mediating role of resource loss.
Article in PloS one, 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
objectivesTo assess the effect of maternal oil spill exposure on children's mental health and examine whether maternal resource loss mediated this relationship.
methods445 mother-child pairs from the Women and Their Children's Health Study in Louisiana (2012-2016) were examined. Maternal oil spill exposure from the 2010 Deepwater Horizon Oil Spill was measured at Wave 1 (2012-2014), while children's mental health and maternal resource loss were assessed at Wave 2 (2014-2016). Structural equation modeling estimated the direct and indirect effects of maternal oil spill exposure on children's mental health through maternal resource loss.
resultsMothers (mean age 42 years (SD 7.7) and children (mean age 13 years (SD 2.2)) were interviewed. Maternal oil spill exposure was not directly related to children's mental health (est = -0.08, p = 0.436). However, exposure was associated with increased maternal resource loss (est = 0.45, p < .0001), which was associated with worse children's mental health (est = 0.27, p < .0001). Maternal oil spill exposure was compatible with an indirect negative effect on children's mental health (i.e., worse mental health scores) mediated by resource loss (est = 0.12, p < 0.005).
conclusionFindings suggest maternal oil spill exposure indirectly affects children's mental health through resource loss. Interventions mitigating resource loss are vital for supporting children's mental well-being after disasters.
