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

backgroundThe mechanisms of severe malarial anemia and cerebral malaria, which are extreme manifestations of Plasmodium falciparum malaria, are not fully understood.

methodsChildren aged <6 years from southern Zambia presenting to the hospital with severe malarial anemia (n = 72), cerebral malaria (n = 28), or uncomplicated malaria (n = 66) were studied prospectively. Children with overlapping severe anemia and cerebral malaria were excluded.

resultsLow interleukin 10 concentrations had the strongest association with severe anemia (standard β = .61; P < .001) followed by high tumor necrosis factor α and sFas concentrations, low weight-for-age z scores, presence of stool parasites, and splenomegaly (standard β = .15-.25; P ≤ .031); most of these factors were also associated with lower reticulocytes. Greater parasitemia was associated with higher interleukin 10 and tumor necrosis factor α concentrations, whereas sulfadoxizole/pyrimethamine therapy and lower weight-for-age z scores were associated with lower interleukin 10 levels. Thrombocytopenia and elevated tissue plasminogen activator inhibitor 1 levels had the strongest associations with cerebral malaria (standard β = .37 or .36; P < .0001), followed by exposure to traditional herbal medicine and hemoglobinuria (standard β = .21-.31; P ≤ .006).

conclusionsPredictors of severe malarial anemia (altered immune responses, poor nutrition, intestinal parasites, and impaired erythropoiesis) differed from those of cerebral malaria (thrombocytopenia, herbal medicine, and intravascular hemolysis). Improved preventive and therapeutic measures may need to consider these differences.
