1 · What the graph read from it

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 registry

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

Developing dynamic color-tunable room-temperature phosphorescence (RTP) materials with photochromism and time-dependent phosphorescence color (TDPC) presents a promising but highly challenging approach for achieving multilevel anti-counterfeiting applications. Herein, we demonstrate a facile in situ synthesis strategy to photo-responsive color-tunable RTP polymer films with reversible photochromic and TDPC properties, which was achieved through rational integration of carboxyl-functionalized spiropyran (SPCOOH) and luminescent hydrogen-bonded organic framework formed by melamine (ME) and isophthalic acid (IPA) within the PVA amorphous matrix, mediated by synergistic hydrogen-bonding networks. Crucially, UV-induced spiropyran-to-merocyanine (SP→MC) isomerization enables a novel triplet-singlet Förster resonance energy transfer (TS-FRET) pathway between the ME-IPA donor and MC acceptor, achieving precise modulation in afterglow color from cyan to orange. Moreover, the energy transfer creates distinct decay kinetics, thereby endowing the material with TDPC property. Furthermore, their multilevel time-resolved multicolor dynamic anti-counterfeiting applications have been demonstrated. This work establishes a simple and effective strategy for constructing TDPC systems to develop color-tunable RTP materials.
