Figure 4

Receiver operating characteristic (ROC) curves for each of lymphocyte subpopulations (CD3, CD4, CD8, and CD19) individually; combined diagnostic ability of all lymphocyte subpopulations; IgA and IgG combined; TREC and KREC combined and diagnostic ability of TREC, KREC, IgA, and IgG combination in differentiating between “Combined PID” and “Syndromic PID” and “Antibody PID.” “Combined PID” and “Syndromic PID” individuals (n = 53); children diagnosed with “Antibody PID” (n = 120). TREC AUC = 0.79 (95% CI = 0.70–0.87).
