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

Arsenic (As) adsorption onto ferrihydrite (Fh) is an effective method for reducing As concentrations and is commonly used in passive mine drainage treatment. A model that predicts the removal of As(III) and As(V) is essential for designing treatment conditions. In this study, the mechanism of As removal in an As(III)-As(V) coexisting system by Fh at pH 7 was clarified. The presence of As(V) inhibited the surface complexation of As(III) on Fh. X-ray absorption fine structure (XAFS) analysis showed that surface precipitation of FeAsO
