Multivariate linear regression of admission variables of AHRF patients associated with ICU length of stay in patients who survived at discharge (n = 1291).

Multivariate linear regression of admission variables of AHRF patients associated with ICU length of stay in patients who survived at discharge (n = 1291).针对出院时仍存活的急性高碳酸血症呼吸衰竭（Acute Hypercapnic Respiratory Failure，AHRF）患者，以其重症加强护理病房（Intensive Care Unit，ICU）住院时长为关联结局，对其入院变量开展多元线性回归分析，共纳入1291例样本（n=1291）。
