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
Dynamic and reversible control of circularly polarized ultralong room-temperature phosphorescence (CP-OURTP) is highly desirable for time-gated chiroptical photonics. Yet, the simultaneous realization of handedness inversion and large dissymmetry factors remains challenging because inversion typically occurs near a net-chirality cancellation point where the photonic bandgap (PBG) collapses. Here, we report a decoupled bilayer CP-OURTP film that couples a room-temperature phosphorescent polymer emitter with a photoresponsive chiral helical superstructure (CHS) engineered by an antagonistic chirality-offset design. By pairing a high-HTP chiral photoswitch with an oppositely handed static dopant, the net HTP reversibly crosses zero while remaining comparable in magnitude in the two photostationary states, thereby maintaining a robust PBG-emission overlap on both sides of inversion. Consequently, the film delivers reversibly switchable g
