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

In Francisella tularensis, the putative DNA-binding protein PigR works in concert with the SspA protein family members MglA and SspA to control the expression of genes that are essential for the intramacrophage growth and survival of the organism. MglA and SspA form a complex that interacts with RNA polymerase (RNAP), and this interaction between the MglA-SspA complex and RNAP is thought to be critical to its regulatory function. How PigR works in concert with the MglA-SspA complex is not known; previously published findings differ over whether PigR interacts with the MglA-SspA complex, leading to disparate models for how PigR and the MglA-SspA complex exert their regulatory effects. Here, using a combination of genetic assays, we identify mutants of MglA and SspA that are specifically defective for interaction with PigR. Analysis of the MglA and SspA mutants in F. tularensis reveals that interaction between PigR and the MglA-SspA complex is essential in order for PigR to work coordinately with MglA and SspA to positively regulate the expression of virulence genes. Our findings uncover a surface of the MglA-SspA complex that is important for interaction with PigR and support the idea that PigR exerts its regulatory effects through an interaction with the RNAP-associated MglA-SspA complex.
