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

This study investigates spatial variations in soil quality across five distinct land-use types-forest, roadside, agricultural, industrial, and residential-in the Manipal region of southern India. Ten surface soil samples from each land-use category were analysed for physico-chemical properties, geochemical composition, and environmental magnetic parameters to evaluate soil degradation and identify potential pollution sources. Marked variations were observed in electrical conductivity, pH, and salinity, with industrial and roadside soils exhibiting elevated values indicative of anthropogenic impact. Concentrations of potentially toxic elements (PTEs), including Pb, Cr, Cu, and Zn, were significantly higher in roadside and industrial areas, frequently exceeding recommended safety thresholds. Environmental magnetic measurements, such as low-frequency magnetic susceptibility (χ
