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 low-cost, high-performance non-fullerene acceptors is crucial for the commercialization of organic solar cells (OSCs). Here, we introduce a β-side-chain-free molecular design strategy that enables the preparation of two new Y6 derivatives, JSM5 and JSM6, with substantially reduced synthetic complexity and cost. Single-crystal X-ray analysis reveals an unusual tetrameric packing, originating from the removal of the β-alkyl chains in the structure. Importantly, this packing unlocks multiple S···N intermolecular interactions between the benzothiadiazole cores, driving γ-shaped molecular conformations to establish efficient layer-by-layer 3D charge transport pathways and exhibit superior intermolecular connectivity. Consequently, remarkably high short-circuit current densities (J
