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

The conducting polymer polypyrrole nanocones wrapped by metal cobalt (Co/PPy) are a promising platform for the detection of sodium nitrite, which can be obtained by an electrochemical deposition technique under a mild condition. Co/PPy nanocone arrays combined the high conductivity and large specific surface area of PPy nanocones with the redox properties of metal cobalt, and their 3D structure can provide more active sites for nitrite detection. Owing to the microstructure and excellent electrical properties of the nanocomposite, Co/PPy nanocone arrays were convenient to construct a high-performance nitrite sensor. The microscopic morphology and composition of Co/PPy nanocone arrays were characterized by SEM, FT-IR, XPS, and XRD, and their electrochemical performances were also investigated. The experimental results showed that Co/PPy nanocones exhibited excellent performance for nitrite determination. The sensors were used for the determination of nitrite in pickled Chinese cabbage and water samples, and the results were consistent with those of spectrophotometry. Hence, the synthesized Co/PPy nanocone arrays have a broad application prospect in food safety, environmental protection, and industrial manufacturing.
