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 developed a radiometric assay by which the antiplasmodial effects of phagocytic cells can be quantitated. This assay was used to examine the effects of recombinant human tumor necrosis factor alpha (TNF-alpha) on the killing of Plasmodium falciparum by human neutrophils. Data presented demonstrated that neutrophils engulf and destroy P. falciparum, but substantial killing of parasites required the presence of either heat-labile or heat-stable opsonins. While recombinant TNF-alpha at concentrations of 5 to 50,000 U/ml showed no direct effects on the parasite, this cytokine augmented the antimalarial activity of neutrophils at doses of 20 to 250 U/10(6) neutrophils. The results suggest that TNF-alpha is an important component of the immune phagocytic effector mechanisms which are involved in destruction of the malarial parasite.
