iKIR score interaction terms with protective HLA class II drivers in a subcohort without HLA class I drivers.

After removal of class I drivers from the cohort (remaining cohort: N = 5,420), we modelled risk of T1D for each protective genotype and included iKIR score in the model as a continuous variable interacting with the HLA class II genotype (). The coefficient for the interaction term was in the expected direction for all genotypes and significant for 4 frequent genotypes.
