Detection of tracheal branching with computerized tomography: The relationship between the angles and age-gender

Table 3 Relationship between age and angles

Variables (coronal)	r	P
Right-left main	0.064	0.014
R upper-intermedius	-0.098	<0.001
R middle-lower	0.167	<0.001
L upper-lower	-0.070	0.007

R upper-intermedius: The angle of the right upper lobe bronchus and the right intermedius bronchus in the coronal plane; R middle-lower: The angle of the right middle lobe bronchus and the right lower lobe bronchus in the coronal plane; L upper-lower: The angle of the left upper lobe bronchus and the left upper lobe bronchus in the coronal plane.
