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

We investigated the kinetics of tissue-specific mRNA expression and systemic production of tumor necrosis factor alpha (TNF-alpha) and the kinetics of splenic expression of mRNAs of gamma interferon (INF-gamma) and interleukin-4 (IL-4), cytokines that may regulate TNF-alpha production, during the early phase of blood-stage infection with Plasmodium chabaudi AS. Northern blot analysis revealed that resistant C57BL/6 mice, which clear the infection by 4 weeks, had higher levels of TNF-alpha mRNA in the spleen and liver early during infection that did susceptible A/J mice, which succumb to the disease 10 days after initiation of infection. Treatment of resistant mice with a polyclonal anti-TNF-alpha antibody confirmed the protective role of TNF-alpha early during the course of infection. Furthermore, resistant C57BL/6 mice also expressed high levels of mRNA of IFN-gamma (a Th1 marker) and low levels of mRNA of IL-4 (a Th2 marker) in the spleen, whereas susceptible A/J mice had low levels of IFN-gamma mRNA but high levels of TNF-alpha mRNA in the liver and had high levels of TNF-alpha protein in serum, as measured by enzyme-linked immunosorbent assay, later during infection just before death occurred. These results demonstrate that a Th1-associated increase in TNF-alpha mRNA expression in the spleen early during infection correlates with resistance to P. chabaudi AS, whereas increased TNF-alpha mRNA levels in the liver and excessive levels of the TNF-alpha protein in serum later during infection correlate with susceptibility. Thus, the role of the TNF-alpha during malaria appears to depend on the timing and site of its expression and the presence of cytokines regulating its production.
