Data shown are the adjusted 𝑅² calculated by the linear regression log(FEV1 DRS) = log(FVC DRS) and the Spearman correlation coefficient between the two variables log(FEV1 DRS) and log(FVC DRS), for the three levels of BMI and for our three populations (AHR+ patients, AHR− patients, and total population).
