4

The correlation of the angle between left principal bronchus and trachea and the ratio of residual volume and total lung capacity among three groups were positively correlative , and the other parameters of lung function were negatively correlative ( P < 0.01 ) .

3组患者左主支气管与气管角度与残气量/肺总量呈正相关，与其他肺功能参数呈负相关（P<0.01）。
