Notes: aIt should be noted that the CU group included all CU patients aged above 60 years. Studies that reported specifically for CSU or CIndU subtypes were also included in the subgroups of CSU and CIndU. bOne patient could have more than one personal history of atopy or one comorbidity. Comorbidity and history of atopy were only showed information from papers which mentioned about each disease. cIt should be noted that the studies of Urbach, Lindelof et al, and Chen et al reported only the number of patients with malignancy, other comorbidities were not identified. dTotal IgE level measured by ImmunoCAP method were reported in three studies, Ban et al (n=37), Romano et al (n=1), and Nettis et al (n=32), which reported about CU, CSU, and CSU, respectively. Referring to the National Center for Health Statistics, Centers for Disease Control and Prevention, the normal range of total IgE based on ImmunoCAP method is 0–119 kU/L. eTotal IgE level measured by Pharmacia CAP method was reported in only one study, Staubach et al (n=4), which reported about CSU. fTotal IgE level measured by Nephelometry method was reported in only one study, Kulthanan et al (n=1), which reported about CSU.
