Notes: The test result variable(s), MPA diameter, RPA diameter, LPA diameter, and MPA/DAo, have at least one tie between the positive actual state and the negative actual state groups. Statistics may be biased.
a
Under the nonparametric assumption.
b
Null hypothesis: true area =0.5.
Abbreviations: MPA, main pulmonary artery; RPA, right pulmonary artery; LPA, left pulmonary artery; AAo, ascending aorta; DAo, descending aorta; sig, significance.
