Comparison of RAW and sGAW disturbance within each group of diseases and specific obstructive disease. Each panel is divided into three sections indicating group of diseases and level of disturbance of parameters within each group. Obstructive group is additionally divided into three subsections representing specific obstructive diseases. Panels a and c/ RAW and sGAW using standard normality limit for disturbance (>150 %, < 50 % of predicted values); Panels b and d/ RAW and sGAW using statistically drawn limits of healthy subgroup for disturbance; Disturbance is indicated with the cross hatch in the figure; Data from N = 976 (RAW) and N = 778 (sGAW) subjects, respectively
