A recombinant RNA bacteriophage system to identify functionally important nucleotides in a self-cleaving ribozyme.
Article in Virology journal, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundRNA bacteriophages like Qbeta and MS2 are well known for their high mutation rate, short infection cycle and strong selection against foreign inserts. The hammerhead ribozyme (HHRz) is a small self-cleaving RNA molecule whose active residues have previously been identified by mutational analysis of each individual base. Here the functionally important bases of HHRz were determined in a single screening experiment by inserting the HHRz into the genome of MS2.
findingsThe minimal HHRz of satellite Tobacco ringspot virus was cloned into the genome of RNA bacteriophage MS2. Sequence analysis of the surviving phages revealed that the majority had acquired single base-substitutions that apparently inactivated the HHRz. The positions of these substitutions exactly matched that of the previously determined core residues of the HHRz.
conclusionsNatural selection against a ribozyme in the genome of MS2 can be used to quickly identify nucleotides required for self-cleavage.
