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

backgroundThe human CYP3A gene cluster codes for cytochrome P450 (CYP) subfamily enzymes that catalyze the metabolism of various exogenous and endogenous chemicals and is an obvious candidate for evolutionary and environmental genomic study. Functional variants in the CYP3A locus may have undergone a selective sweep in response to various environmental conditions.

objectiveThe goal of this study was to profile the allelic structure across the human CYP3A locus and investigate natural selection on that locus.

methodsFrom the CYP3A locus spanning 231 kb, we resequenced 54 genomic DNA fragments (a total of 43,675 bases) spanning four genes (CYP3A4, CYP3A5, CYP3A7, and CYP3A43) and two pseudogenes (CYP3AP1 and CYP3AP2), and randomly selected intergenic regions at the CYP3A locus in Africans (24 individuals), Caucasians (24 individuals), and Chinese (29 individuals). We comprehensively investigated the nucleotide diversity and haplotype structure and examined the possible role of natural selection in shaping the sequence variation throughout the gene cluster.

resultsNeutrality tests with Tajima's D, Fu and Li's D* and F*, and Fay and Wu's H indicated possible roles of positive selection on the entire CYP3A locus in non-Africans. Sliding-window analyses of nucleotide diversity and frequency spectrum, as well as haplotype diversity and phylogenetically inferred haplotype structure, revealed that CYP3A4 and CYP3A7 had recently undergone or were undergoing a selective sweep in all three populations, whereas CYP3A43 and CYP3A5 were undergoing a selective sweep in non-Africans and Caucasians, respectively.

conclusionThe refined allelic architecture and selection spectrum for the human CYP3A locus highlight that evolutionary dynamics of molecular adaptation may underlie the phenotypic variation of the xenobiotic disposition system and varied predisposition to complex disorders in which xenobiotics play a role.
