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
Wide-bandgap (WBG) perovskites are promising top-cell absorbers for tandem photovoltaics but suffer from unbalanced nucleation-growth driven by strong coordination between polar aprotic solvents and perovskite precursors. This promotes the formation of hexagonal intermediate polytypes, stacking defects, halide-cation migration, and phase segregation. Although long-chain alkyl ammonium chlorides are used to control crystallization, the role of volatile ammonium chloride (AC) in altering the precursor chemistry and crystallization pathways in WBG perovskites remains unexplored. Present study, shows that AC weakens precursor-solvent coordination and destabilizes undesired hexagonal polytypes. In situ characterizations indicate that AC induces high-valence, de-intercalated solvated iodoplumbate complexes that inhibit the sol-gel state and balance nucleation-growth kinetics. Concurrently, Cl-rich intermediates provide heterogeneous nucleation sites and, via cation exchange between NH
