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

Candida glabrata, an opportunistic fungal pathogen, adheres to mammalian epithelial cells; adherence is mediated primarily by the Epa1 adhesin. EPA1 is a member of a large gene family of ≈ 23 paralogues, which encode putative adhesins. In this study, we address how EPA1 transcription is regulated. Our data show that EPA1 expression is subject to two distinct negative regulatory mechanisms. EPA1 transcription is repressed by subtelomeric silencing: the Sir complex (Sir2-Sir4), Rap1, Rif1, yKu70, and yKu80 are required for full repression. Activation of EPA1 occurs immediately after dilution of stationary phase (SP) cells into fresh media; however, transcription is rapidly repressed again, limiting expression to lag phase, just as the cells exit stationary phase. This repression following lag phase requires a cis-acting regulatory negative element (NE) located in the EPA1 3'-intergenic region and is independent of telomere proximity. Bioinformatic analysis shows that there are 10 copies of the NE-like sequence in the C. glabrata genome associated with other EPA genes as well as non-EPA genes.
