Note: ^*Non-normally distributed continuous data are presented as M [P25, P75]. G1: Mild pulmonary atelectasis (with a degree of atelectasis less than 30%). G2: Moderate pulmonary atelectasis (with a degree of atelectasis ranging from 30–50%). G3: Severe pulmonary atelectasis (with a degree of atelectasis exceeding 50%)
