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

Plasma levels of pro- and anti-inflammatory cytokines of Plasmodium falciparum-infected patients with severe malaria (SM; n = 62) and uncomplicated malaria (UM; n = 69) from Sri Lanka were assessed. SM patients had significantly higher levels of TNF-alpha (P < 0·01), IL-6 (P < 0·01), and IL-10 (P < 0·05) compared to the UM patients. Plasma IL-2 levels of these patients were undetectable. TNF-alpha levels of a third group of patients with uncomplicated P. falciparum malaria, who were recruited during their fever episodes (UMF; n = 14) were significantly higher than those of the UM patients (P < 0·001) and comparable to SM patients. Plasma IFN-gamma levels of SM patients were higher compared to UM patients, but was not statistically significant. Body temperature in both SM and UMF groups were significantly higher compared to UM group, whereas percentages of parasitemia in all three groups were comparable. Analysis of plasma TNF-alpha levels and the ratio of TNF-alpha/IL-10 in UM (n = 34) and SM (n = 34) patients carrying TNF1 and TNF2 allelic types showed that SM patients carrying TNF2 had significantly higher TNF-alpha levels as well as TNF-alpha/IL-10 ratio compared to UM patients carrying TNF1, UM patients carrying TNF2 and SM patients carrying TNF1 (P < 0·05). These results suggest that the high circulating TNF-alpha levels and the inadequate IL-10 response in the SM patients carrying TNF2 allele could have contributed to the development of severe falciparum malarial disease.
