Alterations in ribosomal protein L19 that decrease the fidelity of translation.
Article in Biochimie. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Ribosomal protein L19 is an essential ribosomal protein and is a component of bridge B8, one of the protein-RNA bridges linking the large and small ribosomal subunits. Bridge B8 also contributes to the accuracy of translation by affecting GTPase activation by ribosome-bound aminoacyl tRNA-EF-Tu•GTP ternary complexes. Previous work has identified a limited number of accuracy-altering alterations in protein L19 of Salmonella enterica and Thermus thermophilus. Here, we have targeted the Escherichia coli rplS gene encoding L19 for mutagenesis and have screened for mutants with altered levels of miscoding. We have recovered 14 distinct L19 mutants, all of which promote increased stop codon readthrough, but do not have major effects on subunit association or cell growth. Examination of the E. coli 70S ribosome structure indicates that the amino acid substitutions cluster in three distinct regions of L19 and thereby potentially affect its interactions with L14 and 16S rRNA.
