(A) unPAD cohort (89 patients): serum immunoglobulins (g/l) at diagnosis. Each column is divided into four parts, depending on the IgG levels; those in the light purple section with IgG ≤ 1.0 g/l; those in the dark purple section with IgG>1.0 ≤ 3.0 g/l; those in the yellow section with IgG >3.0 ≤ 6.5 g/l and those in the orange section with IgG > 6.5 g/l. (B) For comparison: European CVID cohort (Chapel et al., 334 patients): serum immunoglobulins (g/l) at diagnosis. Unabridged from Chapel et al. (18). Permission was obtained from the editor in chief of Blood to use the previously published (B).
