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

The DARC (Duffy antigen/receptor for chemokines) gene, also called Duffy or FY, encodes a membrane-bound chemokine receptor. Two malaria parasites, Plasmodium vivax and Plasmodium knowlesi, use DARC to trigger internalization into red blood cells. Although much has been reported on the evolution of DARC null alleles, little is known about the evolution of the coding portion of this gene or the role that protein sequence divergence in this receptor may play in disease susceptibility or zoonosis. Here, we show that the Plasmodium interaction domain of DARC is nearly invariant in the human population, suggesting that coding polymorphism there is unlikely to play a role in differential susceptibility to infection. However, an analysis of DARC orthologs from 35 simian primate species reveals high levels of sequence divergence in the Plasmodium interaction domain. Signatures of positive selection in this domain indicate that species-specific mutations in the protein sequence of DARC could serve as barriers to the transmission of Plasmodium between primate species.
