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

Electrochemiluminescence (ECL) has emerged as an important analytical method, but the scarcity of effective emitters significantly hinders its broader application. In this work, an amine-rich silica isoporous membrane (A-SIM) was fabricated on an indium tin oxide (ITO) electrode based on a modified Stöber-solution growth approach using an anionic template. Subsequently, the negatively-charged gold nanoclusters (AuNCs) were electrophoretically encapsulated within the positively-charged nanochannels of A-SIM, resulting in a robust aggregation-induced ECL (AIECL) platform of AuNCs@A-SIM/ITO. When compared to other configurations, such as homogeneous dispersion, drop-casting on the electrode, and encapsulation within unmodified SIM, the aggregated AuNCs encapsulated within A-SIM exhibited a remarkable AIECL effect, achieving an ECL efficiency of 17.89%. In contrast, the presence of cyanide ions (CN
