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

The outer membrane (OM) of Gram-negative bacteria is an asymmetric lipid bilayer that serves as a barrier to the environment. During infection, Gram-negative bacteria remodel their OM to promote survival and replication within host tissues. Salmonella rely on the PhoPQ two-component regulators to coordinate OM remodeling in response to environmental cues. In a screen for mediators of PhoPQ-regulated OM remodeling in Salmonella Typhimurium, we identified PbgA, a periplasmic domain-containing transmembrane protein, which binds cardiolipin glycerophospholipids near the inner membrane and promotes their PhoPQ-regulated trafficking to the OM. Purified-PbgA oligomers are tetrameric, and the periplasmic domain contains a globular region that binds to the OM in a PhoPQ-dependent manner. Thus, PbgA forms a complex that may bridge the envelope for regulated cardiolipin delivery. PbgA globular region-deleted mutant bacteria are severely attenuated for pathogenesis, suggesting that increased cardiolipin trafficking to the OM is necessary for Salmonella to survive within host tissues that activate PhoPQ.
