Figure S1.
Panel A shows a stacked bar plot illustrating the distribution of HLA-DQ genotypes among five groups: Non-CeD Control, EHR, Self-Report, EHR plus Self-Report, and Seropositive. The x-axis represents the percent, and the y-axis lists the groups. The plot highlights the frequency of HLA-DQ2.5, with percentages indicated above the bars. Panel B presents a table comparing sex, genetic ancestry, race, ethnicity, and HLA-DQ genotype between EHR and Self-Report groups. The table includes counts and percentages for each category, with p-values indicating statistical significance. Panel C displays a violin plot comparing polygenic risk scores between participants identified by EHR and those identified by self-report. The x-axis labels the identification methods, and the y-axis shows the polygenic score. The plot includes a p-value indicating the comparison's significance.
Comparison of multiple variables between CeD participants identified by EHR and self-reported. (A) Stacked plot showing the distribution of HLA-DQ genotypes among CeD participants from the five groups before removing those without compatible HLA-DQ haplotypes. (B) Comparison of sex, genetic ancestry, race, ethnicity, and HLA-DQ genotype among CeD participants with compatible HLA-DQ genotypes. (C) Comparison of PRSs between participants identified by EHRs only and those identified by self-report only.
