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

Heavy metal contamination in acidified agricultural soils poses significant environmental and health risks. This study presents the development of a cost-effective dual-functional adsorbent, the attapulgite-oyster shell (ATP-OS) composite, engineered for the simultaneous removal of co-contaminated Cd(II) and Pb(II) ions. The ATP-OS composite was synthesized through thermal treatment at 700 °C, facilitating a synergistic interaction between attapulgite (ATP) and oyster shell (OS) powders. Characterization revealed enhanced dispersibility, increased active site density, and an expanded specific surface area, contributing to superior adsorption capacities of 197 mg g
