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

The par post-segregational killing locus present on Enterococcus faecalis plasmid pAD1 was the first Type I toxin-antitoxin system described in Gram-positive bacteria. Translation of the 33 amino acid Fst toxin, encoded on RNA I, is suppressed by a 66 nucleotide regulatory RNA, RNA II. RNA I and RNA II are transcribed convergently and interact at dispersed regions of complementarity, establishing a stable complex that accumulates in plasmid-containing cells. RNA II is slowly removed from the complex, allowing translation of RNA I in plasmid-free segregants. Intramolecular structures are also important for regulating translation of RNA I. The Fst toxin contains a putative transmembrane domain and is believed to exert its function at the bacterial cytoplasmic membrane, although its precise target and mode of action have yet to be determined. Numerous chromosomal homologs of pAD1 par have been identified in Gram-positive bacteria suggesting that this locus may play important roles in cellular function.
