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

Whereas the mechanism of nonopsonic phagocytosis of Pseudomonas aeruginosa has been described, the bacterial ligands required are poorly understood. To identify the requisite bacterial ligands, studies with isogenic mutants of P. aeruginosa PAK lacking pili, flagella, and the RpoN sigma factor were undertaken. The RpoN mutant, lacking pili, flagella, and nonpilus adhesins, bound poorly and was resistant to ingestion by both macrophages and neutrophils. Pili were not absolutely required for binding or phagocytosis of P. aeruginosa. The presence of a flagellum was not required for binding of P. aeruginosa to macrophages but was critical for the subsequent internalization of the bacterium, suggesting that this factor or a surface ligand associated with its assembly was responsible for stimulation of nonopsonic phagocytosis.
