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 3' box of the human class II snRNA genes is required for proper 3' processing of transcripts, but how it functions is unclear. Several lines of evidence suggest that termination of transcription occurs at the 3' box and the terminated transcript is then a substrate for processing. However, using nuclear run-on analysis of endogenous genes, we demonstrate that transcription continues for at least 250 nucleotides beyond the 3' box of the U2 genes. Although in vivo footprinting analysis of both the U1 and U2 genes detects no protein-DNA contacts directly over the 3' box, a series of G residues immediately downstream from the 3' box of the U1 gene are clearly protected from methylation by dimethylsulfate. In conjunction with the 3' box of the U1 gene, this in vivo footprinted region causes termination of transcription of transiently transfected U2 constructs, whereas a 3' box alone does not. Taken together, these results indicate that the 3' box is not an efficient transcriptional terminator but may act as a processing element that is functional in the nascent RNA.
