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 developed a self-healing, anti-corrosive coating based on a novel nanocomposite formulation of 8-hydroxyquinoline-5-sulfonic acid-zinc doped polyaniline (HQZn-PA) incorporated into an epoxy matrix. The chemical composition and surface morphology of the synthesized nanocomposite were thoroughly characterized using Fourier transform infrared spectroscopy, X-ray diffraction, nuclear magnetic resonance, and scanning electron microscopy. Electrochemical impedance spectroscopy and potentiodynamic polarization tests confirmed the outstanding corrosion resistance and self-healing efficiency of the coating. The synthesized HQZn-PA demonstrates enhanced anticorrosive properties through the synergistic effects of its constituents. Polyaniline (PA) contributes anodic protection and forms a barrier layer, while the chelation of zinc by 8-hydroxyquinoline-5-sulfonic acid (HQZn) improves PA compatibility within the polymer matrix and functions as an organic corrosion inhibitor. This dual action strengthens corrosion resistance through both anodic and cathodic protection mechanisms. The HQZn-PA nanocomposite reduced the corrosion rate of epoxy coating by 450× compared and maintained an impedance modulus of 1.03 × 10
