Representative data for the upper limit of normal for airway radius along the distance of the airway tree centerline from the origin of each lobar bronchus stratified by sex

Sex- and height-stratified upper limit of normal (ULN) values for airway radius along the airway centerline were determined using CT data from the health check-up cohort (n=445). Each data sheet includes the distance from the origin of each lobar bronchus (mm) and airway radius (mm) for right upper, middle, and lower lobes (RUL, RML, and RLL, respectively) and left upper and lower lobes (LUL and LLL, respectively). Although the actual analysis was performed at 1-cm height intervals for males (155–185 cm) and females (141–173 cm), this dataset includes representative data for the ULN for airway radius at 5-cm intervals.
