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 low-cost electrochemical sensor based on a graphite screen-printed carbon electrode modified with nickel nanoparticles was developed for the sensitive determination of mefenamic acid (MFA), an emerging environmental contaminant due to its persistence and incomplete removal in wastewater treatment, which may lead to endocrine-disrupting effects in aquatic systems. The incorporation of nickel nanoparticles into the graphite-based ink significantly increased the electroactive surface area and enhanced electron transfer kinetics, resulting in improved analytical performance. Morphological and structural analyses confirmed the successful integration of nickel nanoparticles into the electrode matrix. Electrochemical characterization using cyclic voltammetry and electrochemical impedance spectroscopy demonstrated higher faradaic currents and lower charge transfer resistance compared to the unmodified electrode. Under optimized conditions, differential pulse voltammetry provided a well-defined oxidation signal for mefenamic acid, with a linear range from 0.5 to 12.20 µmol L⁻¹, a limit of detection of 69.12 nmol L⁻¹, and a sensitivity of 0.434 µA L µmol
