Multivariate analysis of determinants associated with sleep disturbances (PSQI>5) in bronchiectasis patients.

†In multivariate analysis, determinants with a P value ≤0.1 in preceding univariate analyses, including age, BMI, education, employment status, depression score, anxiety score, 24-hour sputum volume, daytime cough score, nighttime cough score, PA colonization, and MRC dyspnea score, were initially included, and were then eliminated using backward selection.

†在多变量分析中，首先纳入前期单变量分析中P值≤0.1的影响因素，包括年龄、体重指数（Body Mass Index，BMI）、受教育程度、就业状况、抑郁评分、焦虑评分、24小时痰量、日间咳嗽评分、夜间咳嗽评分、铜绿假单胞菌定植（PA colonization）及MRC呼吸困难评分（MRC dyspnea score），随后采用后退法进行变量剔除。
