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

Malaria infection is initiated by sporozoite invasion of hepatocytes and asexual reproduction of liver stages, processes that are regarded to be "clinically and diagnostically silent." Merozoites, which egress from hepatocytes, infect erythrocytes in periodic cycles and induce disease. How the host innate immune system contributes to disease outcomes and to the induction of effector cells during malaria remains unclear. Likewise, how the initial liver stages may shape responses to blood-stage parasites is unknown. Here, using both sporozoite- and blood-stage-induced infections with the rodent malaria parasite Plasmodium berghei ANKA, we show that the MyD88 and Toll-like receptor 2/4 (TLR2/4) pathways play critical roles in the development of experimental cerebral malaria (ECM). Strikingly, an absolute dependence on MyD88 and TLR2/4 was observed when infections were initiated with sporozoites. In addition, we show that caspase-1 activation of interleukin-1β (IL-1β) and IL-18, which is associated with the inflammasome pathway, does not contribute to P. berghei ANKA-induced immunopathology. Consistent with these data, prophylactic cover with the IL-1β antagonist anakinra did not reduce the incidence of ECM. Therefore, we propose that protection against ECM due to loss of TLR signaling functions is caused by effector mechanisms other than IL-1β activation.
