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

Pyocyanin is a phenazine pigment produced by the bacterium Pseudomonas aeruginosa and found in human lung secretions. Micromolar concentrations of pyocyanin inhibited the bioactivity of endothelium-derived relaxing factor (EDRF) generated from bovine pulmonary-artery endothelium in response to bradykinin. This inhibition was reversed by perfusing the EDRF-bioassay system with pyocyanin-free buffer for 15 min, but persisted in the presence of superoxide dismutase (20 units/ml). When nitric oxide, the major component of EDRF, was passed into an aqueous solution of pyocyanin in the absence of O2, a rapid colour change occurred from blue to pink; m.s. analysis of the products showed that the pyocyanin had been converted into a nitrosylated species.
