Environmental and Household Sources Associated with Elevated Blood Lead Levels Among Mexican Women of Childbearing Age: A Community-Based Screening Study.
Article in Toxics, 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
backgroundLead (Pb) exposure remains a significant public health concern, particularly among women of childbearing age, because of its adverse effects on maternal-child health. Although lead-glazed ceramics (LGC) for cooking or storing food are a well-recognized source of Pb exposure in Mexico, other environmental and household sources remain insufficiently characterized.
objectiveTo identify environmental and household factors associated with elevated blood lead levels (BLLs) among women of childbearing age participating in a community-based screening in Mexico City.
methodsWe conducted a cross-sectional analysis of 158 women aged 18-40 years. Capillary BLLs were measured using the LeadCare
resultsThe prevalence of elevated BLLs was 31%. Women reporting both past and current use of LGC had higher odds of elevated BLLs than women who had never used LGC (adjusted OR = 9.43; 95% CI: 1.85-48.15). Living in or regularly visiting a recently remodeled home (adjusted OR = 3.21; 95% CI: 1.45-7.11) and living near a highway (adjusted OR = 2.41; 95% CI: 1.07-5.48) were also independently associated with elevated BLLs. LGC use was the largest contributor to the model performance (47.46%), followed by home remodeling (31.78%) and proximity to highways (20.76%).
conclusionsOur findings support LGC as an important source of Pb exposure while identify home remodeling and residential proximity to highways as additional sources associated with elevated BLLs. Together, these findings broaden the understanding of Pb exposure pathways among women of childbearing age and support the need for prevention and screening strategies.
