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

Lead is a neurotoxic metal. No safe blood lead level (BLL) has been identified in children; the CDC reference value was lowered to 3.5 µg/dL in 2021, while Mexico's regulatory threshold remains at 10 µg/dL. Lead-glazed earthenware is the main documented source of pediatric exposure in Mexico. We studied children 0-15 years insured by the Mexican Social Security Institute (IMSS) in two Jalisco municipalities: Tonalá (
