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

Mutations in the GTPase center of Escherichia coli 23S rRNA were characterized in vivo as UGA-specific nonsense suppressors. Some site-directed mutations did not exhibit suppressor activity and were interspersed among suppressor mutations. Our results demonstrate the involvement of the two adjacent loops of this conserved rRNA structure in UGA-dependent translation termination and, taken with previous in vitro analyses and with consideration of the crystal structure of the GTPase center RNA, indicate that nucleotides 1067, 1093, 1094, and 1095 are sites of interaction with release factor 2.
