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

objectivesPlasmodium falciparum multidrug resistance protein 1 (pfmrp1) has recently emerged as an important determinant of drug resistance and mutations in the gene have been associated with several drugs. The aim of this study was to understand the level of genetic diversity in pfmrp1 and to determine the association of different mutations with altered drug susceptibilities of P. falciparum.

methodsWe analysed 193 sequences of pfmrp1 from South-East Asia, west Asia, Africa, Oceania and South America. We measured the level of genetic diversity and determined signatures of selection on the gene. In vitro susceptibilities of 28 P. falciparum isolates from north-east Myanmar to a panel of seven commonly used antimalarials were determined. Statistical analysis was performed to determine the association of different mutations with in vitro drug susceptibilities.

resultsA total of 28 single nucleotide polymorphisms were identified in 193 sequences, of which 22 were non-synonymous. Whereas mutations in the pfmrp1 gene were conserved among different countries within a continent, they were different between continents. Seven non-synonymous mutations were identified in the north-east Myanmar isolates; all were relatively frequent in this region as well as in other neighbouring countries. Molecular evolutionary analysis detected signatures of positive selection on the gene. Moreover, some mutations in this gene were found to be associated with reduced susceptibilities to chloroquine, mefloquine, pyronaridine and lumefantrine.

conclusionsEvidence of the positive selection of pmfrp1 and its association with the susceptibilities of parasites to multiple drugs signifies its potential as an important candidate for monitoring drug resistance.
