Association between rhinitis and urticaria
The occurrence of rhinitis was significantly associated with urticaria based on the data of 11 studies (OR, 2.67; 95% CI, 2.625–2.715).14,17,21,22,34,42,45,47,50,61,66 When examining the association of AR in patients with CU, the corresponding pooled Ors were 3.132 (95% CI, 3.073–3.193).17,22,47,50,61 Moreover, the corresponding pooled ORs for AR in patients with CSU was 2.854 (95% CI, 2.665–3.055, 2 studies).22,50 Only one study21 examined the corresponding pooled OR of AU in patients with rhinitis, revealing a negative association (OR, 0.35l 95% CI, 0.28–0.43).
The corresponding pooled ORs were 2.447 (95% CI, 2.326–2.573) and 1.338 (95% CI, 1.250–1.43) according to the studies reporting on the co-occurrence of rhinitis and urticaria in children and adolescents patients or adults patients separately. Only one study17 has reported on the association between rhinitis and urticaria in male and female patients, and the corresponding pooled ORs were 1.63 (95% CI, 1.52–1.76) and 1.56 (95% CI, 1.47–1.66), respectively.
