highly significantP = 0.047
Despite the large sample size, neither association is highly significant (P = 0.047 and 0.02 respectively) and the P-values have not been adjusted for multiple hypothesis testing.
Despite the large sample size, neither association is highly significant (P = 0.047 and 0.02 respectively) and the P-values have not been adjusted for multiple hypothesis testing.
However, these associations were only of borderline significance, and so need to be interpreted with some caution.
There was also evidence for a borderline significant effect for the rare allele of rs4988344, which was associated with an increased risk in a dose-dependant manner (OR = 1.15 [95%CI 1.02–1.30], P-trend = 0.02), compared with common homozygotes.
The samples were split into two sets in order to save DNA and reduce genotyping costs: the first set (n = 2270 cases and 2280 controls) was genotyped for all SNPs and the second set (n = 2203 cases and 2280 controls) were then tested for those SNPs that showed marginally significant associations in set 1 (P-heterogeneity or P-trend<0.1).
