Significant (p value <0.05) associations indicated in bold

Power: indicates power in the SCHS study to detect reported associations at these SNPs given reported effect estimates (Yokoyama et al. 2007; Wang et al. 2006) and MAF of SCHS dataset; NA: power not calculated for previously reported traits that were not measured in SCHS; TAF: test allele frequency

* Indicates significant association for the same n-3 trait in the SCHS data
