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 work presents PMMA/PANI-WO₃ nanocomposites with tunable optical and electrical properties, designed for optoelectronic and energy storage applications. The novelty of this study lies in the incorporation of WO₃ nanoparticles into a PMMA/PANI blend, enabling a simultaneous enhancement of dielectric behavior, ionic conductivity, and optical response. XRD and FTIR analyses confirmed reduced crystallinity and strong polymer-filler interactions. Optical studies revealed a notable decrease in the band gap from 3.80 eV for pure PMMA/PANI to 3.18 eV at the highest WO₃ loading, accompanied by improved refractive index. Thermal analysis demonstrated enhanced stability, while impedance spectroscopy showed an increase in ionic conductivity by nearly three orders of magnitude (10⁻⁸ → 10
