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

A rapid, simple, and accurate voltammetric method for quantifying total inorganic arsenic in rice was described in this work. The simplified sample pretreatment involved the addition of a mixed solution of nitric acid and L-cysteine, which facilitated the simultaneous extraction and speciation of arsenic (As(III)). To eliminate interference from complex rice matrices, magnetic composites were employed to absorb copper and other potential interference. Furthermore, As(III) was detected using linear stripping voltammetry with screen-printed electrodes modified in-situ with gold nanoparticles and L-cysteine, enhancing both sensitivity and selectivity. With this strategy, the methodology demonstrated good resistance to interference and high sensitivity, with a detection limit of 0.018 mg/kg. A comparative analysis between this method and liquid chromatography coupled with inductively coupled plasma mass spectrometry (ICP-MS) showed a good correlation with an R
