7433 individuals with 296 type 1 diabetes events (155 in the first 6 years and 141 after 6 years of age) were included in the analysis because values of SNPs and/or weight at 12 months of age were missing. For each SNP, the minor allele is indicated and children with this allele (yes) were compared with children without it (no)
