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
Plasmonic nanostructures have attracted considerable interest for their ability to manipulate light at the nanoscale. The optical response of these metallic architectures is greatly sensitive to changes in their surrounding environment, which makes them particularly interesting for sensing applications. Here, we report a versatile and highly sensitive plasmonic sensing platform that combines the surface lattice resonances (SLRs), sustained by 2D gratings of metal nanoparticles, and the exceptional refractive index tunability offered by ZIF-8 metal-organic framework (MOF) films. The SLRs provide narrow resonances that strongly depend on the surrounding refractive index, which can be modulated via solvent exchange in the ZIF-8. The plasmonic 2D arrays were fabricated using templated-assisted assembly of metal colloids; a scalable and gentle process that enabled the study of different ZIF-8/grating configurations. First, we studied ZIF-8 films on top of the 2D arrays, where an optimized concentration of the colloidal dispersion allowed dynamic and reversible ON/OFF tuning of the SLR response. Second, we explored the role of the refractive index mismatch between substrate and ZIF-8 superstrate. Finally, we fabricated 2D plasmonic gratings completely embedded within ZIF-8 layers, achieving enhanced sensing performance with a refractive index sensitivity of 427 ± 19 nm·RIU
