Measures are Pearson’s correlation coefficients (p values).
ACQ, Asthma Control Questionnaire; GSAQ, GERD Symptoms Assessment Questionnaire; SABA, short-acting β agonist use; SOB, shortness of breath.
Dark grey boxes indicate p value significance <0.01, light grey boxes indicate p value significance <0.05.
Bolded values represent R values ≥0.750. Woken—‘On average, during the past week, how often were you woken by your asthma during the night?’ Morning—‘On average, during the past week, how bad were your asthma symptoms when you woke up in the morning?’ Activities—’In general, during the past week, how limited were you in your activities because of your asthma?’ SOB—’In general, during the past week, how much shortness of breath did you experience because of your asthma?’ Wheeze—’In general, during the past week, how much time did you wheeze?’ SABA—’On average, during the past week, how many puffs/inhalations of short-acting bronchodilator have you used each day?’ FEV1—FEV1 per cent predicted subscale of ACQ represented by a 7-point ordinal scale, FEV1%—FEV1 per cent predicted.
