Prior to treatment, patients treated with beclomethasone and Mometasone showed no difference between the total score of the questionnaire. After treatment, it became clear that the group treated with Mometasone group had a statistically significant reduction in the severity of symptoms (2.0 vs. 3.0, p <0.001), activity (1.6 vs. 2.7, p <0.001), sleep (1.7 vs 2.9 , p <0.001) and psychological effects (1.3 vs 2.7, p <0.001) compared to the group treated with beclomethasone. Overall, the group treated with beclomethasone document more severe adverse effects with respect to mometasone.
