RNA Scanning of a Molecular Machine with a Built-in Ruler.

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
Advanced single-molecule techniques have enabled tracking of nanometer-scale movements of DNA and RNA motor proteins in real time. Previously, we reported an ATP-independent diffusion of transactivation response RNA binding protein (TRBP) on dsRNA, yet the mechanistic details remain elusive. Using single-molecule fluorescence assays, we demonstrate that the diffusion activity of TRBP is coordinated by an independent movement of two subdomains, dsRBD1 and dsRBD2, in which the diffusion distance is determined by the length of a flexible linker domain that connects the two dsRBDs. When the linker is shortened, the diffusion distance is reduced proportionally, suggesting a ruler-like function of the linker domain. Diffusion stalls upon encountering a physical barrier in the form of an RNA:DNA hybrid segment or bulky secondary structures, indicating a dsRNA scanning mode of TRBP. The results display a plausible mechanism of TRBP in scanning for pre-miRNA or pre-siRNA as proper substrates for the RNAi pathway.
