Genome-wide assessment for genetic variants associated with ventricular dysfunction after primary coronary artery bypass graft surgery.
Article in PloS one, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT01258231 (Identification of Genomic Predictors of Adverse Events After Cardiac Surgery), which is not on this map. Cited by 1 paper.
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.

Abstract
backgroundPostoperative ventricular dysfunction (VnD) occurs in 9-20% of coronary artery bypass graft (CABG) surgical patients and is associated with increased postoperative morbidity and mortality. Understanding genetic causes of postoperative VnD should enhance patient risk stratification and improve treatment and prevention strategies. We aimed to determine if genetic variants associate with occurrence of in-hospital VnD after CABG surgery.
methodsA genome-wide association study identified single nucleotide polymorphisms (SNPs) associated with postoperative VnD in male subjects of European ancestry undergoing isolated primary CABG surgery with cardiopulmonary bypass. VnD was defined as the need for ≥2 inotropes or mechanical ventricular support after CABG surgery. Validated SNPs were assessed further in two replication CABG cohorts and meta-analysis was performed.
resultsOver 100 SNPs were associated with VnD (P<10(-4)), with one SNP (rs17691914) encoded at 3p22.3 reaching genome-wide significance (P(additive model) = 2.14×10(-8)). Meta-analysis of validation and replication study data for 17 SNPs identified three SNPs associated with increased risk for developing postoperative VnD after adjusting for clinical risk factors. These SNPs are located at 3p22.3 (rs17691914, OR(additive model) = 2.01, P = 0.0002), 3p14.2 (rs17061085, OR(additive model) = 1.70, P = 0.0001) and 11q23.2 (rs12279572, OR(recessive model) = 2.19, P = 0.001).
conclusionsNo SNPs were consistently associated with strong risk (OR(additive model)>2.1) of developing in-hospital VnD after CABG surgery. However, three genetic loci identified by meta-analysis were more modestly associated with development of postoperative VnD. Studies of larger cohorts to assess these loci as well as to define other genetic mechanisms and related biology that link genetic variants to postoperative ventricular dysfunction are warranted.
