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
An emerging class of two-dimensional semiconductor materials, metal-organic chalcogenolates (MOCs), have garnered significant attention due to the strong excitonic effects arising from their intrinsic soft, hybrid multiquantum-well structures. However, modifying excitonic transitions that strongly couple to the argentophilic networks and constructing their structure-property relationships in MOCs remain daunting challenges. Here, we use silver phenylselenolate (AgSePh) as a model system to manipulate excitonic behavior and uncover the fundamental photophysical mechanisms through pressure engineering. A bright broadband Stokes-shifted emission is observed in AgSePh crystals along with the disappearance of blue narrow emission upon compression, which is attributed to the pressure-induced carrier transformation from free exciton to self-trapping exciton states. The considerable compressibility of the Ag-Se inorganic monolayer, driven by weakly bound argentophilic interactions, generates pronounced argentophilic intralayer distortion while simultaneously enhancing exciton-phonon coupling and excitonic oscillator strength. This work demonstrates the remarkable tunability of excitonic properties in layered MOCs.
