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

Helix 69 of Escherichia coli 23S rRNA has important roles in specific steps of translation, such as subunit association, translocation, and ribosome recycling. An M13 phage library was used to identify peptide ligands with affinity for helix 69. One selected sequence, NQVANHQ, was shown through a bead assay to interact with helix 69. Electrospray ionization mass spectroscopy revealed an apparent dissociation constant for the amidated peptide and helix 69 in the low micromolar range. This value is comparable to that of aminoglycoside antibiotics binding to the A site of 16S rRNA or helix 69. Helix 69 variants (human) and unrelated RNAs (helix 31 or A site of 16S rRNA) showed two- to fourfold lower affinity for NQVANHQ-NH(2). These results suggest that the peptide has desirable features for development as a lead compound for novel antimicrobials.
