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

Prior studies suggest Staphylococcus aureus exotoxins are not produced when the organism is cultured in human blood. Human blood was fractionated into plasma and water-lysed red blood cells, and it was demonstrated that mixtures of alpha and beta globins of hemoglobin (as low as 1 mug/mL) inhibited S. aureus exotoxin production while increasing production of protein A and not affecting bacterial growth. Pepsin but not trypsin digestion destroyed the ability of alpha and beta globin to inhibit exotoxin production. Exotoxin production by both methicillin-resistant and methicillin-susceptible organisms was inhibited. Production of streptococcal pyrogenic exotoxin A by Streptococcus pyogenes was unaffected by alpha and beta globin chains but was inhibited when produced in S. aureus. Use of isogenic S. aureus strains suggested the targets of alpha and beta globin chains, leading to inhibition of staphylococcal exotoxins, included the two-component system SrrA-SrrB. delta hemolysin production was also inhibited, suggesting the two-component (and quorum sensing) system AgrA-AgrC was targeted. The alpha and beta globin chains represent promising molecules to interfere with the pathogenesis of serious staphylococcal diseases.
