Correlation of nasal symptoms and endoscopic scores with eustachian tube function in HDM-allergic rhinitis patients. a The Pearson correlation coefficient between ETDQ-7 and itching VAS scores (normal distribution) was r = 0.0707 (p = 0.5947). b The Spearman correlation coefficient between ETDQ-7 and nasal obstruction VAS scores (non-normal distribution) was r = 0.5124 (p < 0.0001). c The Pearson correlation coefficients between ETDQ-7 and sneezing scores (normal distribution) was r = 0.2203 (p = 0.0937). d The Pearson correlation coefficients between ETDQ-7 and rhinorrhoea scores (normal distribution) was r = − 0.03006 (p = 0.8212). e The Pearson correlation coefficient between ETDQ-7 and nasal endoscopic scores (normal distribution) was r = 0.7328 (p < 0.0001)
