The OB-fold proteins of the Trypanosoma brucei editosome execute RNA-chaperone activity.
Article in Nucleic acids research, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
Sequence-deficient mitochondrial pre-mRNAs in African trypanosomes are substrates of a U-nucleotide-specific RNA editing reaction to generate translation-competent mRNAs. The reaction is catalyzed by a macromolecular protein complex termed the editosome. Editosomes execute RNA-chaperone activity to overcome the highly folded nature of pre-edited substrate mRNAs. The molecular basis for this activity is unknown. Here we test five of the OB-fold proteins of the Trypanosoma brucei editosome as candidates. We demonstrate that all proteins execute RNA-chaperone activity albeit to different degrees. We further show that the activities correlate to the surface areas of the proteins and we map the protein-induced RNA-structure changes using SHAPE-chemical probing. To provide a structural context for our findings we calculate a coarse-grained model of the editosome. The model has a shell-like structure: Structurally well-defined protein domains are separated from an outer shell of intrinsically disordered protein domains, which suggests a surface-driven mechanism for the chaperone activity.
