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
The South Australian regional city of Port Pirie has a long history of environmental lead contamination caused by smelting operations that have resulted in elevated blood lead levels in local children. This study examines the potential exposure of children to lead as a result of consuming eggs produced by domestic chickens kept in a lead-contaminated environment. Lead concentrations were measured in eggs, chicken enclosure soil, chicken feed and forage vegetation collected from a domestic site in Port Pirie. Eggs produced in the vicinity of the operating smelter had higher whole-egg lead concentrations (median: 0.09 mg/kg; range: 0.03-0.19 mg/kg) than control eggs (median: 0.002 mg/kg; range: 0.002-0.005 mg/kg). Soil and forage vegetation were identified as potential lead sources for the chickens in this study. The impact of remediating potential lead sources accessed by the chickens was examined and remedial actions were found to be only partly effective with a three-fold reduction in lead concentrations in eggs. Estimated lead intake for a 2-year-old child consuming these eggs indicated that a diet rich in eggs could more than double the child's daily lead exposure from dietary sources. Eggs produced by chickens housed in residential backyards are a readily avoidable additional source of lead exposure for children living in this industrial community, where all environmental lead sources contribute to an unacceptable daily intake.
