Figure 1.
Classical HLA haplotype/alleles association with type 1 diabetes diagnosed at <7 years old (red circle; mean log-odds ratio age at diagnosis ± 95% CI), 7–13 years old (green circle; mean log-odds ratio age at diagnosis 7–13 ± 95% CI), and ≥13 years old (blue circle; mean log-odds ratio age at diagnosis ≥13 ± 95% CI), from a multinomial logistic regression. Left panel shows the log-odds ratios, with a dashed red line showing a log-odds ratio of 0. The right panel shows the association statistics from a likelihood ratio test comparing a multinomial logistic regression constraining the log-odds ratios from the <7 to ≥13 groups to be equal compared with an unconstrained model. The red dotted line shows nominal significance in heterogeneity (P < 0.05), and the red dashed line shows Bonferroni-corrected significance in heterogeneity. T1D, type 1 diabetes.
