ANGPTL4 and autosomal agammaglobulinemia: In our study population, higher VAT expression of ANGPTL4 was associated with the presence of AGM with an OR = 5.1 (95% C.I.: 1.2–23; p = 0.02; χ2 test applied) and with an AUC = 0.76 (95% C.I.: 0.63 – 0.88; p < 0.001) at the ROC curve adjusted for age and sex (Figure 2).
