General QoL assessment of the patients
We observed that the median QoL scores in all patients group was 32 (min-max: 1-89). Female participants reported higher QoL scores indicating poor QoL (p= 0.009). The patient group with less than 13 years of education had higher QoL scores compared to the group with more than 13 years of education (p= 0.015). Higher QoL scores were also observed in the IVIG treatment group when compared to the SCIG treatment group (p= 0.005). We did not observe significant correlation between age, BMI, duration of disease and QoL scores (p>0.05). The QoL scores ​​of our patients and Italian and Norwegian groups were given according to gender, age, education, IVIG, SCIG and BMI groups in Table 3.
