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

In this study, an electrochemical sensor based on graphene (GR)-, gold nanoparticles (AuNPs)-, and poly(L-serine) (PSer)-modified glassy carbon electrode (GCE) was reported for the efficient determination of the synthetic antioxidant propyl gallate (PG) in foodstuffs. The surface composition of the working electrode was optimized using the one-factor-at-a-time method. The surface morphology of the PSer/AuNPs/GR/GCE was examined using the scanning electron microscopy (SEM) technique. To evaluate the electrochemical characteristics of the sensor, cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) studies were carried out. Linear range, detection limit, and sensitivity of the PSer/AuNPs/GR/GCE were determined by differential pulse voltammetry (DPV) and found to be 6.1 × 10
