Higher alveolar fluid clearance is independently associated with female gender

Variable	Unstandardized coefficient (95% CI)	p value
Gender	7.78 (2.32–13.23)	0.006
Age	0.05 (−0.09–0.19)	0.470
SAPSII	−0.01 (−0.15–0.13)	0.904

After adjusting for age and severity of illness (SAPSII), female gender remained independently associated with a higher rate of alveolar fluid clearance in patients with acute lung injury. In this linear regression model, the absolute rate of AFC was 7.8% faster in women versus men, 0.05% faster for each additional year of age (p=NS) and 0.01% slower for every increase in SAPS II by 1 (p=NS).
