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

objectiveProprotein convertase subtilisin-like kexin type 9 (PCSK9) is a newly discovered serine protease that plays a key role in regulating plasma low density lipoprotein (LDL) cholesterol levels. Both rare mutations and common variants in the coding regions of PCSK9 affect LDL cholesterol levels and coronary heart disease risk, as well as response to lipid-lowering therapy.

methodsThe authors characterized the patterns of variation at the PCSK9 locus in African-Americans and European-Americans using resequenced data from the SeattleSNPs database (pga.gs.washington.edu). The authors performed a test of population differentiation and the long-range haplotype test to detect signatures of recent position selection on PCSK9.

resultsA significantly high FST (a measure of population differentiation) between African-Americans and European-Americans was noted for single nucleotide polymorphism (SNP) rs505151 (FST=0.309). The long-range haplotype test was suggestive of non-neutral evolution of two SNPs, rs505151 and rs562556 that are associated with elevated LDL cholesterol levels ('gain-of-function' mutations). The modes of selection were different between African-Americans and European-Americans. The authors observed signals of recent positive selection on the ancestral allele of nonsynonymous SNP rs505151 (E670G, P=0.0227 and P=0.0001 in theoretical and empirical distribution, respectively) and the derived allele of nonsynonymous SNP rs562556 (I474V, P=0.0227 and 0.0001) in African-Americans, whereas in European-Americans the ancestral allele of SNP rs562556 (P=0.1320 and 0.0370) appeared to be under positive selection.

conclusionThe authors' findings suggest that evolutionary dynamics may underlie the 'gain-of-function' mutations in PCSK9 that are associated with higher LDL cholesterol levels.
