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
In this manuscript pairs of flexibly linked silver nanoparticles, so called silver plasmon rulers, are synthesized using a rational DNA programmed self-assembly procedure. The plasmon resonance energy (E(res)) versus distance relationship is calibrated for dimers comprising sphere-like silver nanoparticles with diameters of 41.0 ± 4.6 nm and surface-to-surface separations between 1-25 nm. Single dimer Rayleigh scattering spectra are correlated with structural information of the same dimers obtained through transmission electron microscopy with 1 nm spatial resolution. The calibration reveals different plasmon coupling regimes. For larger separations the plasmon resonance energy red-shifts continuously with decreasing center-to-center distance (L) until the L to diameter (D) ratio reaches a value of L/D ≈ 1.05. For shorter interparticle separations E(res) does not further red-shift; instead the slope of E(res)(L/D) levels off, and the measured resonance energies become broadly distributed. Overall, the spectral response of nearly touching dimers indicates that the plasmon coupling does not continue to intensify with decreasing interparticle separation at very short separations. The performed characterization of the distance dependent plasmon coupling forms the quantitative foundation for applications of plasmon rulers in plasmon coupling microscopy and nanoplasmonic devices with defined near- and far-field properties.
