Biochemical Validation of a Second Guanidine Riboswitch Class in Bacteria.
Article in Biochemistry, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 69 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
Recently, it was determined that representatives of the riboswitch candidates called ykkC and ykkC-III directly bind free guanidine. Guanidine-binding ykkC motif RNAs, now renamed guanidine-I riboswitches, were demonstrated to commonly regulate the expression of genes encoding guanidine carboxylases, as well as others encoding guanidine efflux proteins such as EmrE and SugE. Likewise, genes encoding similar efflux proteins are associated with ykkC-III motif RNAs, which have now been renamed guanidine-III riboswitches. Prior to the validation of guanidine as the ligand for these newly established riboswitch classes, another RNA motif was discovered by comparative genomic analysis and termed mini-ykkC because of its small size and gene associations similar to those of the original ykkC motif. It was hypothesized that these distinct RNA structures might respond to the same ligand. However, the small size and repetitive nature of mini-ykkC RNAs suggested that it might respond to ligand via the action of a protein factor. Herein, we demonstrate that, despite its extremely simple architecture, mini-ykkC motif RNAs constitute a distinct class of guanidine-sensing RNAs, called guanidine-II riboswitches. Surprisingly, each of the two stem-loop structures that comprise the mini-ykkC motif appears to directly bind free guanidine in a cooperative manner. These findings reveal that bacteria make extensive use of diverse guanidine-responsive riboswitches to overcome the toxic effects of this compound.
