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

objectiveCytochrome P450 2B6 (CYP2B6) is involved in the metabolism of artemisinin drugs, a novel series of antimalarials. Our aim was to analyze the prevalence of the most commonly observed CYP2B6 alleles in malaria-endemic populations of West Africa (WA) and Papua New Guinea (PNG).

methodsUsing a post-PCR ligation detection reaction-fluorescent microsphere assay, frequencies of CYP2B6*1A, *2, *3, *4, *5, *6, *7, and *9 were determined in WA (n=166) and PNG (n=174). To compare with the results of previous studies, we also determined the allele frequencies in 291 North Americans of various ethnic groups.

resultsSignificant differences were observed between WA and PNG for the frequencies of alleles CYP2B6*1A (45% vs 33%, P = 0.003), *2 (4% vs. 0%, P<0.001), *6 (42% vs 62%, P<0.001), and *9 (8% vs 1%, P<0.001), and genotypes *1A/*9 (9% vs 0%, P<0.001) and *6/*6 (17% vs 43%, P<0.001). The frequencies of CYP2B6 genotypes in the populations were in Hardy-Weinberg equilibrium, except for PNG where an overall significant deficit of heterozygosity was observed (H (O)=0.431, H (E)=0.505, P=0.004). The allele frequencies in Asian-Americans and Caucasians-Americans were comparable to those documented for Japanese and Caucasian populations.

conclusionsCYP2B6 variants, previously shown to affect metabolism of a variety of drugs, occur in WA and PNG, and there are significant genetic differences at the CYP2B6 locus in these populations. It may be important to determine if these differences alter the efficacy of artemisinin drugs.
