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

Circularly polarized luminescence (CPL) imaging of biomolecules using designed chiral probes holds significant promise for biochemical and analytical applications. In this work, we report two chiral hetero[9]helicene multi-resonant thermally activated delayed fluorescent (MR-TADF) organic molecules DDCzBPh and DDCzBPy, consisting of two annulated MR-TADF units to a central naphthyl or quinoxanyl group, respectively, which exhibit simultaneously strong CPL, two-photon absorption, high photoluminescence quantum yields, and long-lived delayed fluorescence. We demonstrate two-photon-excited CPL of TADF emitters, with their circularly polarized brightness of 0.2 GM, demonstrating their potential for CPL biological imaging.
