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

Integrating recognition and signal output into chiral covalent organic frameworks (CCOFs) remains challenging because conventional frameworks are static, with recognition events decoupled from signal transduction. Herein, we report a dynamic coordination strategy to construct chiral covalent organic frameworks (CCOFs) that enable a recognition-triggered reconstruction and reconstruction-induced chemiluminescence (CL) response. Chirality was imparted to an achiral bipyridine-based COF through reversible coordination of enantiopure cysteine (Cys) to framework-mounted cobalt centers, yielding l/d-Cys@Co-TFB-DABP. This design established a competitive ligand displacement mechanism, wherein enantiomer recognition selectively displaces coordinated Cys and triggers
