Influence of Actinobacillus pleuropneumoniae and its metabolites on porcine alveolar epithelial cells.
Article in Infection and immunity, 1996. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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.
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 effect of Actinobacillus pleuropneumoniae and its metabolites on the viability of porcine alveolar epithelial cells was studied by using a neutral-red uptake test. Alveolar epithelial cells were obtained from 5-week-old colostrum-deprived pigs. The purity of these cells as assessed by the modified Papanicolaou stain was 90 to 95%. Incubation of these cells with 10(6) CFU of a biotype 1 serotype 1 strain resulted in death of the alveolar epithelial cells within 1.5 h. A cytotoxic effect was also seen when alveolar epithelial cells were incubated with sterile culture supernatants of biotype 1 serotype 1, biotype 1 serotype 10, and biotype 2 serotype 2 strains or with ApxI, ApxII, or ApxIII produced by recombinant Escherichia coli. Incubation of alveolar epithelial cells with a knockout mutant of the biotype 1 serotype 1 parent strain which is unable to secrete Apx toxins or with its supernatant did not result in death of these cells. These results indicate that cytotoxicity is at least in part due to production of Apx toxins.
