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

Promoter escape involves breaking of the favourable contacts between RNA polymerase (RNAP) and the promoter to allow transition to an elongation complex. The sequence of DNA template that is transcribed during promoter escape (ITS; Initially Transcribed Sequence) can affect promoter escape by mechanisms that are not yet fully understood. We employed a highly parallel strategy utilizing Next Generation Sequencing (NGS) to collect data on escape properties of thousands of ITS variants. We show that ITS controls promoter escape through a combination of position-dependent effects (most prominently, sequence-directed RNAP pausing), and position-independent effects derived from sequence encoded physical properties of the template (for example, RNA/DNA duplex stability). ITS often functions as an independent unit affecting escape in the same manner regardless of the promoter from which transcription initiates. However, in some cases, a strong dependence of ITS effects on promoter context was observed suggesting that promoters may have 'allosteric' abilities to modulate ITS effects. Large effects of ITS on promoter output and the observed interplay between promoter sequence and ITS effects suggests that the definition of bacterial promoter should include ITS sequence.
