  1. CVID_QoL scores are presented as mean (SD). NA = not available, ns = not significant, CVID = common variable immunodeficiency, PAD = primary antibody deficiency, SCIG = subcutaneous immunoglobulin, IVIG = intravenous immunoglobulin, BMI=Body mass index.*Comparison of Global CVID_QoL scores between the Norwegian and the Italian cohorts.**Data only available for the patients recruited through the CRD seminar (n = 32).†Reported as significantly different from age ≤ 50 years (p = 0.04) in Quinti et al. [8].‡Reported as significantly different from BMI > 18.5 (p = 0.02) in Quinti et al. [8]. Otherwise, no significant differences were found for the global CVID_QoL scores within the Italian or Norwegian cohorts
