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
CuO thin films are attractive candidates for solar cell absorber layers due to their natural abundance and suitable band gap. This study investigates the potential of pristine and doped (Zn, Mg, and Al) CuO thin films in Si-based heterojunction solar cells through both experimental fabrication and SCAPS-1D simulations under AM 1.5 illumination. Simulations revealed that doping significantly enhanced the solar cell efficiency, increasing it from 5% for pure CuO to over 24% in doped samples, approaching theoretical predictions. However, introducing parasitic resistance reduced the efficiency to 3.99% for pure CuO and 5.77% for Al-doped CuO. Additionally, oxygen defects were found to influence device performance, with higher efficiency observed when interstitial oxygen (
