Table 3
Clinical factors related to high NOSE score (≥50, “moderate to severe problem”): results of univariate and multivariate analysis.
| Prognostic factor | Univariate analysis | Multivariate analysis | Odds ratio | 95% confidence interval | value (Pearson’s chi square) | Odds ratio | 95% confidence interval | value (Pearson’s chi square) |
| Nasal obstruction visual analog scale: ≥50 | 11.1 | 4.40–28.11 | < 0.0001 | 17.6 | 5.83–61.6 | < 0.0001 | Internal nasal valve angle: <10 degrees (grade 1 or 2)‡ | 4.34 | 2.31–8.12 | < 0.0001 | NS | NS | = 0.2433 | External nasal deformity: mild to severe (grades 2–4) | 3.59 | 1.79–7.22 | = 0.0002 | 4.63 | 1.14–19.9 | = 0.0339 | Allergic rhinitis: yes | 3.36 | 1.83–6.16 | < 0.0001 | 5.5 | 1.77–18.7 | = 0.0041 | Use of nasal steroids: yes | 2.30 | 1.08–4.89 | = 0.0266 | NS | NS | = 0.2262 | Cottle maneuver: moderate to significant improvement (grade 3 or 4) | 2.28 | 1.03–5.07 | = 0.0399 | NS | NS | = 0.2862 | Nasal septal deviation: mild to severe (grades 2–4) | 2.05 | 1.13–3.72 | = 0.0168 | NS | NS | = 0.1906 | History of nasal trauma: yes | 1.89 | 0.94–3.80 | = 0.0697 | NS | NS | = 0.6106 |
