AOR, adjusted odds ratio; CI, confidence interval; FSSG, frequency scale for symptoms of gastro-oesophageal reflux disease; IIPs, idiopathic interstitial pneumonias. ^aHosmer and Lemeshow test for cough intensity and frequency, p = 0.175 and p = 0.972, respectively. ^bConnective tissue disease-associated interstitial lung disease or chronic hypersensitivity pneumonia as reference category. ^cThe data for intensity and frequency of cough were divided at the median to create categorical variables
