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

Herein, we designed a dual DNP-caged near-infrared probe, N-Bu-DCIB-2DNP, by conjugating dicyanoisophorone (DCI) with an N-alkylated benzimidazole (B) through double vinylene linkers. This probe features two responsive sites-the DNP ether on the donor and the DNP-functionalized electron-deficient quaternary carbon on the DCI unit-to enable a cascade thiolysis strategy. The probe exhibits distinct dual-emission fluorescence signals at 610 nm and 745 nm with large Stokes shifts, and achieves a rapid response to H
