1 · What the graph read from it

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.

2 · The registry

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

GE81112 is a tetrapeptide antibiotic that binds to the 30S ribosomal subunit and specifically inhibits P-site decoding of the mRNA initiation codon by the fMet-tRNA anticodon. GE81112 displays excellent microbiological activity against some Gram-positive and Gram-negative bacteria in both minimal and complete, chemically defined, broth, but is essentially inactive in complete complex media. This is due to the presence of peptides that compete with the antibiotic for the oligopeptide permease system (Opp) responsible for its illicit transport into the bacterial cells as demonstrated in the cases of Escherichia coli and Bacillus subtilis. Mutations that inactivate the Opp system and confer GE81112 resistance arise spontaneously with a frequency of ca. 1 × 10(-6), similar to that of the mutants resistant to tri-l-ornithine, a known Opp substrate. On the contrary, cells expressing extrachromosomal copies of the opp genes are extremely sensitive to GE81112 in rich medium and GE81112-resistant mutations affecting the molecular target of the antibiotic were not detected upon examining >10⁸ cells of this type. However, some mutations introduced in the 16S rRNA to confer kasugamycin resistance were found to reduce the sensitivity of the cells to GE81112.
