Landscape-scale controls on trace metals partitioning and mobility in tropical soils affected by legacy lead smelting.

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 long-term legacy of a decommissioned lead smelter in Santo Amaro, Bahia (Brazil), has produced one of the most metal-contaminated urban areas worldwide. This study investigates the spatial distribution, geochemical partitioning, and potential mobility of trace metals across contrasting landscape units, namely hillslope and floodplain soils. A total of 120 soil samples were analyzed using portable X-ray fluorescence (XRF), scanning electron microscopy coupled with energy-dispersive spectroscopy (SEM-EDS), and the BCR sequential extraction procedure. XRF results revealed extremely high concentrations of Pb (up to 24,962 mg kg
