Surface enhanced electrochemiluminescence of Ru(bpy)3(2+).
Article in Scientific reports, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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.
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
Surface enhanced spectroscopy such as surface enhanced Raman spectrum (SERS) and surface enhanced fluorescence have been investigated extensively in the past two decades. Herein, we present experimental evidence to demonstrate the existence of a new surface enhanced spectroscopy, namely, surface enhanced electrochemiluminescence (SEECL). Our investigation indicates that the electrochemiluminescence (ECL) response of the Ru(bpy)3(2+)-tri-n-propylamine (TPrA) system could be significantly enhanced when the working electrode is modified with gold nanoparticle-SiO2 core-shell nanocomposites (AuNP@SiO2). It is worth noting that comparing with a working electrode modified with pure SiO2 nanoparticles, the electrochemical responses of the two electrodes were quite similar, but the ECL signal of the AuNP@SiO2 modified electrode was ~5 times higher than that of the SiO2 nanoparticles modified electrode. Thus we infer that the localized surface plasmon resonance (LSPR) of the AuNPs could be a major contribution to the ECL enhancement. Our investigations also demonstrate that the ECL enhancement is closely related to the thickness of the SiO2 layer. As much as 10 times ECL enhancement (comparing with the ECL intensity of bare electrode) is observed under the optimal conditions. The possible mechanism of the SEECL phenomenon is also discussed.
