Association of basic critical care echocardiography screening-derived abnormalities with log(length of stay) in patients with acute respiratory distress syndrome

Major BCCE-detected abnormalities	Log (length of stay, ICU)		Log (length of stay, hospital)
	Univariate ratio (95% CI)a	Multivariate ratio (95% CI)b	Univariate ratio (95% CI)a	Multivariate ratio (95% CI)b
Screened patients with acute respiratory distress syndrome (Berlin Definition)
