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

Achieving molecular chirality with enantiostability in purely π-conjugated foldamers remains a substantial challenge due to inherently weak π-π stacking interactions and facile racemization. Herein, we introduce a novel design strategy employing synergistic intramolecular 3D π-π stacking networks within a 1,8-diarylnaphthalene framework, enabling foldamers to exhibit extraordinary configurational stability. A systematic series of quinoxaline- and phenazine-based foldamers incorporating carbazole (CZ) and diphenylamine (DPA) donors were synthesized, with chiral configurations stabilized through complementary face-to-face and laterally offset π-π stacking interactions. Single-crystal X-ray analyses and computational studies confirmed the formation of complex intramolecular π-networks, providing exceptional racemization barriers (ΔG
