Quality of Life
Quality of life was measured using the CU-Q2oL. The CU-Q2oL is a CSU-specific health-related QoL questionnaire consisting of 23 questions. The questions cover different aspects of CSU’s impact on patients’ lives including pruritus, swelling, daily life activities, sleep, appearance, and limitations. CU-Q2oL scores range from 23 to 115, with a higher score indicating stronger impairment of health-related QoL.13,14
