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 registryThe 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.

6 · The paper itselfAbstract
Wide-bandgap perovskite solar cells (WBG-PSCs) are essential for high-efficiency tandem photovoltaics, yet conventional mixed-halide formulations suffer from photoinduced halide segregation. While pure-iodide WBG-PSCs offer a fundamental solution, their development is hindered by the distinct crystallization kinetics of A-site cations, which lead to severe compositional inhomogeneity, coupled with lead toxicity. Herein, we report a multifunctional ionic liquid, 1-propylsulfonate-3-methylimidazolium trifluoromethanesulfonate ([SO
