Envelope glycoprotein (gp120) from HIV-1 enhances Mycobacterium avium growth in human bronchoalveolar macrophages; an effect mediated by enhanced prostaglandin synthesis.
Article in Clinical and experimental immunology, 1994. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Human bronchoalveolar lavage (BAL) macrophages were obtained from normal human volunteers and infected with an AIDS-associated strain of Mycobacterium avium. Infected cells were exposed to purified envelope glycoprotein (gp120) from HIV-1 or to the recombinant non-glycosylated gp120 fragments PBI-RF and PBI-IIIB. Native gp120 increased Myco. avium growth in human cells from six separate donors, whereas the non-glycosylated fragments of gp120 had no such effect. Moreover, gp120 induced a substantial secretion of prostaglandin E2 (PGE2) from macrophages; inclusion of indomethacin blocked the enhanced permissiveness of infected cells treated with gp120. Soluble CD4 also neutralized the effect of gp120. Overall, these results indicate a role for gp120 in the susceptibility of AIDS patients to Myco. avium infections, mediated by an enhanced PGE2 release.
