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

Transcription factors (TFs) may activate or repress gene expression through an interplay of different mechanisms, including RNA polymerase (RNAP) recruitment, exclusion, and initiation. However, depending on the regulated promoter identity, TF function can vary, and the principles underlying this context dependence remain unclear. We demonstrate an inverse scaling relationship between the promoter's basal activity and its regulation by a given TF. Specifically, activation is weaker and repression is stronger on stronger promoters. This scaling applies to both activators and repressors, which suggests a common underlying mechanism where TFs regulate expression by stabilizing RNAP binding at the promoter. The consequence of this relationship is that TFs buffer expression by affecting constant regulated expression levels across promoters of different basal activity, ensuring homeostatic control despite genetic or environmental changes.
