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 begins when an infected mosquito injects saliva containing Plasmodium sporozoites into the host skin. The immune response against a mosquito saliva protein, AgTRIO, reduces Plasmodium infection and can work in combination with antibody against the Plasmodium circumsporozoite protein (CSP). We have now developed a chimeric peptide, PfAg, containing regions from Plasmodium falciparum CSP (PfCSP) and AgTRIO. Mice administered PfAg generated robust humoral responses against both PfCSP and AgTRIO. After exposure to PfCSP-expressing Plasmodium berghei-infected mosquitoes, PfAg-immunized inbred C57BL/6 and outbred CD-1 mice had significantly improved survival compared with control animals. These data will aid in the development of a new malaria vaccine.
