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 study evaluates the repurposed application of an expired non-sedating antihistamine drug (ENSAD), fexofenadine hydrochloride, as a high-performance "green" corrosion inhibitor for copper in 1.0 M HCl. Gravimetric results demonstrate a concentration-dependent inhibition efficiency reaching 96.4% at 120 ppm, with remarkable long-term stability (> 92.5% efficiency after 72 h). Adsorption behavior followed the Langmuir isotherm model, indicating the formation of a stable monolayer. The calculated Gibbs free energy (∆G
