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

We used a transcriptional run-on assay in permeabilized yeast cells to study the distribution of RNA polymerase II (pol II) complexes before and after activation by Gal4. Polymerases were found engaged on the gene at the 5' end before activation, but only appeared at the 3' end after activation. Mutations of the pol II C-terminal domain (CTD), the CTD kinase Kin28 and the holoenzyme subunit Srb2 all inhibited the formation of 3' polymerases in response to activator. However, these mutations did not inhibit the establishment of polymerases at the 5' end. The differences between 3' and 5' ternary complexes suggest that they represent qualitatively distinct 'activated' and 'non-activated' forms of polymerase. The results implicate CTD phosphorylation in a switch from 'non-activated' transcription, which is confined to the 5' end, to an 'activated' mode that traverses the length of the gene.
