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

Outer membrane protein A (OmpA) of Escherichia coli is a paradigm for the biogenesis of outer membrane proteins; however, the structure and assembly of OmpA have remained controversial. A review of studies to date supports the hypothesis that native OmpA is a single-domain large pore, while a two-domain narrow-pore structure is a folding intermediate or minor conformer. The in vitro refolding of OmpA to the large-pore conformation requires isolation of the protein from outer membranes with retention of an intact disulfide bond followed by sufficient incubation in lipids at temperatures of ≥ 26 °C to overcome the high energy of activation for refolding. The in vivo maturation of the protein involves covalent modification of serines in the eighth β-barrel of the N-terminal domain by oligo-(R)-3-hydroxybutyrates as the protein is escorted across the cytoplasm by SecB for post-translational secretion across the secretory translocase in the inner membrane. After cleavage of the signal sequence, protein chaperones, such as Skp, DegP and SurA, guide OmpA across the periplasm to the β-barrel assembly machinery (BAM) complex in the outer membrane. During this passage, a disulfide bond is formed between C290 and C302 by DsbA, and the hydrophobicity of segments of the C-terminal domain, which are destined for incorporation as β-barrels in the outer membrane bilayer, is increased by covalent attachment of oligo-(R)-3-hydroxybutyrates. With the aid of the BAM complex, OmpA is then assembled into the outer membrane as a single-domain large pore.
