The pulmonary arteries were divided into three groups according to the Heath-Edwards classification, such as artery under 100 μm, 100 to 300 μm, or over 300 μm in diameter (designated the 'under 100-μm' group, the '100 to 300-μm' group, and the 'over 300-μm' group, respectively). This table surmised the average stenosis rate in each arterial group. Values are expressed as mean ± standard deviation.
