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

Although the detection of phosphate can be achieved by nickel hydroxide instead of noble metals, the sensitive detection of phosphate using nickel hydroxide transformed into hydroxy nickel oxide needs to be done under alkaline conditions, which is not environmentally friendly. To solve this problem, we prepared flake-shaped nickel hydroxide-sensitive electrodes supported on carbon cloth using a low-consumption one-step method from the new strategy that the specific adsorption of nickel hydroxide to phosphate can change the electrode's surface charge distribution and investigated their performance in detecting phosphate under neutral conditions. The specific adsorption of phosphate changed the charge distribution on the surface of the electrode, improved the electron transfer efficiency, and facilitated the valorization of nickel, while the flake-shaped nickel hydroxide provided more active sites for the electrode, which resulted in a good performance of the nickel hydroxide electrode: a sensitivity of 1530 mA mM
