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

Leukotrienes produced from arachidonic acid by the action of 5-lipoxygenase (5-LO) are classical mediators of inflammatory responses. Recently, it has been demonstrated that leukotrienes also play an important role in host defense against microorganisms. In vitro studies have shown that leukotrienes augmented the anti-mycobacterial activity of neutrophils. In this study, we examined the role of leukotrienes in regulating host response and cytokine generation in a murine model of tuberculosis. Administration of the 5-LO pathway inhibitor MK 886, which reduced lung levels of both the leukotriene B(4) and the anti-inflammatory substance lipoxin A(4) by approximately 50%, increased 60-day mortality from 14% to approximately 57% in Mycobacterium tuberculosis-infected mice, and increased lung bacterial burden by approximately 15-fold. Although MK 886-treated animals exhibited no reduction in pulmonary leukocyte accumulation, they did manifest reduced levels of nitric oxide generation and of the protective type 1 cytokines interleukin-12 and gamma interferon. Together our results demonstrate that 5-LO pathway product(s) - presumably leukotrienes - positively regulate protective Th1 responses against mycobacterial infection in vivo. Moreover, the immunosuppressive phenotype in infected mice observed with MK 886 is most consistent with inhibition of an activator (LTB(4)) rather than a suppressor (LXA(4)) of antimicrobial defense, suggesting the major effect of leukotrienes.
