Also in the Results section, the following sentence should have appeared with the two changes shown in square brackets: ‘Although the observed associations are not significant after correction for multiple testing of SNPs selected for these replication analyses, we observed marginally significant evidence of association of SNP rs11624702 in MDGA2 (MAM domain containing glycosylphosphatidylinositol anchor 2) with response in the ISPC alone ( P =0.061) and [‘and' should read ‘but not'] in the combined ISPC-AMPS-STAR*D meta-analysis ( P =0.029) [‘0.029' should read ‘0.36'], with the minor allele being associated with lower odds of response (that is, worse clinical outcomes)'.
