Table 2 Association between gender and perennial asthma: bivariate logistic regression models adjusted for relevant covariates

From: Gender differences in asthma perception and its impact on quality of life: a post hoc analysis of the PROXIMA (Patient Reported Outcomes and Xolair® In the Management of Asthma) study

   OR gender (Females vs males) [95% CI] OR other covariates* [95% CI]
*Age at baseline (years) n = 335 0.556 [0.252–1.227] 0.988 [0.965–1.011]
*Presence of comorbidity at baseline (no vs yes) n = 335 0.550 [0.249–1.213] 0.705 [0.352–1.414]
*Asthma duration at baseline (years) n = 325 0.541 [0.244–1.199] 0.986 [0.965–1.009]
*Age at diagnosis (years) n = 325 0.558 [0.253–1.232] 1.001 [0.981–1.021]
*N° exacerbations (0 vs ≥ 1) n = 308 0.362 [0.143–0.918] 0.470 [0.176–1.258]
*IgE serum level at baseline (IU/mL) n = 238 0.301 [0.085–1.063] 1.002 [1.000–1.003]
*Smoke (Current/former vs no smoker) n = 335 0.564 [0.256–1.244] 1.425 [0.599–3.394]
*ACQ score (< 4 vs ≥ 4) n = 318 0.534 [0.233–1.227] 0.845 [0.243–2.947]
