Phonon Driven Ferroelectricity and Raman Active Modes in Hybrid Organic-Inorganic Perovskites.
Article in Advanced materials (Deerfield Beach, Fla.), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Hybrid organic-inorganic perovskites (HOIPs) have emerged as promising ferroelectric semiconductors, yet the phonon signatures governing their ferroelectricity remain poorly understood. Here, by analyzing the temperature-dependent Raman peak profiles of highly ordered ferroelectric domains in HOIPs, a framework to systematically investigate the dimensionality (n)-dependent phonons that are critical to ferroelectric behaviour is established. By tracking phonon evolution across the ferroelectric-to-paraelectric phase transition in HOIPs with different n, characteristic modes associated with the ferroelectric symmetry-breaking process are identified. Notably, in the ferroelectric phase of (BA)
