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

Pathogenic bacteria encounter host-imposed manganese (Mn) limitation during infection. Herein we report that in the human pathogen Streptococcus pyogenes, the adaptive response to Mn limitation is controlled by a DtxR family metalloregulator, MtsR. Genes upregulated by MtsR during Mn limitation include Mn (mtsABC) and Fe acquisition systems (sia operon), and a metal-independent DNA synthesis enzyme (nrdFEI.2). To elucidate the mechanism of metal sensing and gene regulation by MtsR, we determined the crystal structure of MtsR. MtsR employs two Mn-sensing sites to monitor metal availability, and metal occupancy at each site influences MtsR regulatory activity. The site 1 acts as the primary Mn sensing site, and loss of metal at site 1 causes robust upregulation of mtsABC. The vacant site 2 causes partial induction of mtsABC, indicating that site 2 functions as secondary Mn sensing site. Furthermore, we show that the C-terminal FeoA domains of adjacent dimers participate in the oligomerization of MtsR on DNA, and multimerization is critical for MtsR regulatory activity. Finally, the mtsR mutant strains defective in metal sensing and oligomerization are attenuated for virulence in a mouse model of invasive infection, indicating that Mn sensing and gene regulation by MtsR are critical processes during S. pyogenes infection.
