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.
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 investigates a dual-protection strategy that combines antimony oxide (Sb₂O₃) nanoparticles with varying contents (10, 20, and 30 ppm) and benzotriazole (BTA) concentrations ranging from 0 to 40 ppm to enhance corrosion resistance in copper alloys. Highlights the development of eco-friendly potentials for reducing industrial costs effectively, against electrochemical deterioration. The combination enhances barrier properties and passivates the copper surface in a 5% NaCl corrosive medium. Open circuit potential (OCP), potentiodynamic polarization, surface studies using SEM-EDX and XPS, and electrochemical impedance spectroscopy (EIS) all verified the synergistic effect of Sb₂O₃ and BTA, showing markedly lower corrosion current densities and improved protective barrier development. The findings demonstrate that the hybrid application of organic molecules and inorganic nanoparticles enhances the chemical stability of the copper surface, in addition to its physical barrier properties. At lower content, combining BTA and Sb₂O₃ nanoparticles enhances the corrosion resistance of copper-based materials by ~ 99.96%.
