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

Immunoglobulin mu alternative RNA processing is regulated during B-cell maturation and requires balanced efficiencies of the competing splice (mum) and cleavage-polyadenylation (mus) reactions. When we deleted sequences 50 to 200 nucleotides beyond the mus poly(A) site, the mus/mum mRNA ratio decreased three- to eightfold in B, plasma, and nonlymphoid cells. The activity could not be localized to a smaller fragment but did function in heterologous contexts. Our data suggest that this region contains an RNA polymerase II pause site that enhances the use of the mus poly(A) site. First, known pause sites replaced the activity of the deleted fragment. Second, the mu fragment, when placed between tandem poly(A) sites, enhanced the use of the upstream poly(A) site. Finally, nuclear run-ons detected an increase in RNA polymerase loading just downstream from the mus poly(A) site, even when the poly(A) site was inactivated. When this mu fragment and another pause site were inserted 1 kb downstream from the mus poly(A) site, they no longer affected the mRNA expression ratio, suggesting that pause sites affect poly(A) site use over a limited distance. Fragments from the immunoglobulin A gene were also found to have RNA polymerase pause site activity.
