HLA-DQA1 and type 1 diabetes mellitus: Nevertheless, to maximize the identification of significant alleles associated with T1D, 2 fields resolution analysis was performed where HLA-DQA1*03:01 allele [17% vs. 9% OR (95% CI) = 2.22 (1.23–4), Pc = 0.04] passed the significance threshold and conferred risk to T1D.
