Giant Band Gap Narrowing under Hydrostatic Pressure in (4FP)
Article in The journal of physical chemistry letters, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
One of the most intriguing properties of hybrid halide perovskites is their structural softness. The interplay between organic and inorganic sublattices leads to a multitude of physical phenomena that are not observed in conventional semiconductors such as III-V materials. One among these is the exceptional band gap tunability under hydrostatic pressure. In this context, tin-based perovskites exhibit a more pronounced effect than their lead-based counterparts. Here, we report on one of the largest band gap tunabilities in this material family. The studied material, layered tin-based (4FP)
