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

Proper 3' end formation of the human pre-snRNAs synthesized by pol II requires the cis-acting 3' box, although the precise function of this element has proved difficult to determine. In vivo, 3' end formation is tightly linked to transcription. However, we have now been able to obtain transcription-independent 3' box-dependent processing in vitro. This finally demonstrates that the 3' end of pre-snRNAs is produced by RNA processing rather than by termination of transcription. The phosphorylated form of the C-terminal domain (CTD) of pol II activates the processing event in vitro, consistent with our previous demonstration of the role of the CTD in pre-snRNA 3' end formation in vivo. In addition, we show that sequences upstream from the 3' box of the U2 snRNA gene influence 3' end formation both in vivo and in vitro.
