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 peanut shell-modified screen-printed carbon electrode (SPE) was developed for the sensing of caffeic acid (CA) in saliva samples using cheap miniaturized analyzer composed of a laptop and an electrochemical workstation. Peanut shells, sourced from abundant biomass residues, were used to fabricate magnetic biochar (MB) and pyrrole-functionalized magnetic biochar (PFMB) with varying pyrrole/Fe ratios through a hydrothermal process. The surface morphology and electrochemical properties of the synthesized PFMB material were analyzed using XRD, FTIR, Raman, SEM, VSM, cyclic voltammetry, and differential pulse voltammetry techniques. The PFMB-modified SPE displayed excellent electrocatalytic response towards CA in a wide linear range from 10 to 600 μM with a low limit of detection of 0.08 μM. The enhanced electrocatalytic response could be ascribed to the synergistic effect of pyrrole-functionalized biochar and Fe
