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
Scalable manufacturing of perovskite solar cells is fundamentally limited by the vulnerability of perovskite crystallization to ambient moisture and oxygen, particularly during blade coating where an extended pre-annealing interval exposes unstable intermediates. Here, we introduce a surface-confined protection strategy to intrinsically stabilize perovskite film formation under ambient conditions. By introducing dipropylammonium trifluoroacetate (DPTA) into the perovskite precursor ink to spontaneously form a dense and self-assembled surface layer, selectively shielding the wet perovskite pre-film from environmental attack during the critical pre-annealing stage. This transient yet effective barrier preserves the PbI
