Occurrence, Risk Factors, and Outcomes of Pulmonary Barotrauma in Critically Ill COVID-19 Patients: A Retrospective Cohort Study

Table 2

Multivariable logistic regression analysis for the risk factors of pulmonary barotrauma. Variables entered in the model are obesity, diabetes, asthma, cancer, lymphocyte count, lactate, d-dimer, corticosteroid treatment, hyperlipidemia, and invasive mechanical ventilation.

Steroid treatment	1.551	0.305	7.887	0.597
Diabetes	1.191	0.212	6.683	0.842
Asthma	1.132	0.200	6.404	0.888
D-dimer level per unit increment	0.967	0.875	1.069	0.510
Lactate level per unit increment	0.895	0.655	1.223	0.487
Hyperlipidemia	0.813	0.259	2.553	0.723
Obesity	0.673	0.193	2.345	0.534
Lymphocyte count per unit increment	0.465	0.130	1.663	0.239
Cancer	0.000	0.000	—	0.999
