We also tested whether using the haplotypes in Block 2 could improve the prediction of stop RT beyond fitting only the most significant single (rs12364283). The likelihood ratio test based on fitting stop RT as a function of rs12364283 genotypes and, separately, as a function of the four haplotypes observed in Block 2 was not significant. Thus, the other SNPs in Block 2 contain little additional information about the relationship between stop RT beyond what rs12364283 explains.
