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 artificial inhibition of expression of genes in Saccharomyces cerevisiae is not a widespread, useful phenomenon. The external guide sequence (EGS) technology, which is well-proven in bacteria and mammalian cells in tissue culture and in mice, can also be utilized in yeast. The TOP2 and SRG1 genes can be inhibited by ∼30% with EGSs in vivo. Results in vitro also show convenient cleavage of the relevant transcripts by RNase P and appropriate EGSs. The feasible constructs shown to date have an EGS covalently linked to M1 RNA, the RNA subunit of RNase P from Escherichia coli. Greater efficiency in cleavage of transcripts can be fashioned using more than one EGS targeted to different sites in a transcript and stronger promoters controlling the EGS constructs.
