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

This work presents the development of an electrochemical sensor based on a starch film extracted from the Babassu coconut mesocarp flour, carbon black (CB), and cobalt phthalocyanine. Scanning-electron microscopy coupled with energy-dispersive spectroscopy confirmed the presence of each component in composite, by confirming alteration of surface morphology and composition. Raman and Fourier-transform infrared spectroscopy also evidenced surface alteration while atomic-force microscopy revealed increase in rugosity after insertion of CB and cobalt phthalocyanine. The developed sensor was applied for the determination of hydroxychloroquine (HCQ) in both environmental and pharmaceutical (tablet) samples, using linear sweep voltammetry and a 0.1 mol L
