Expression of the Group A Streptococcus Fibrinogen-Binding Protein Mrp Is Negatively Regulated by the Small Regulatory RNA FasX.

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.
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
The group A Streptococcus (GAS; Streptococcus pyogenes) causes an elaborate array of human diseases. In part, such variability in disease potential is a consequence of GAS manipulating the expression of a catalogue of virulence factors, with regulation occurring at both the transcriptional and posttranscriptional levels. The GAS small regulatory RNA (sRNA) FasX contributes to this regulatory activity, enhancing expression of the thrombolytic agent streptokinase, and reducing expression of collagen (pili) and fibronectin (PrtF1 and PrtF2) -binding adhesins. Here, we expand insight into the regulatory targets of FasX by identifying the M-related protein (Mrp), a fibrinogen-binding adhesin with anti-phagocytic activity, as a negatively-regulated target of FasX. Importantly, investigation of the consequences of FasX-mediated regulation led to the discovery that FasX is a major positive regulator of GAS survival and proliferation in non-immune whole human blood, with a 30-fold difference in GAS cell numbers between a
