Linear regression analyses on skin blanching response (AUC).

Since FEV1 and RV/TLC are highly correlated to each other, they were not entered in the model simultaneously. Dependent variable is skin blanching response (AUC). Both models were corrected for age, gender, and height. B =  regression coefficient, SE  =  standard error, FEV1 =  forced expiratory volume in one second, FVC  =  forced vital capacity, RV  =  residual volume, TLC  =  total lung capacity, MEF50  =  maximal expiratory flow at 50% of vital capacity, TLCO  =  carbon monoxide transfer factor, VA  =  accessible lung volume. Values in bold represent significant p-values (< 0.05).
