The Validity of Quantifying Pulmonary Contusion Extent by Lung Ultrasound Score for Predicting ARDS in Blunt Thoracic Trauma

Table 5

Relation between LUS contusion score and development of ARDS.

Patients developed ARDS	Contusion score US				χ^2	MCP
	Group A score<4 (n = 31)		Group B score≥4 (n = 19)
	No.	%	No.	%
No	30	96.8	8	42.1	18.554	<0.001
Mild	0	0.0	1	5.3
Moderate	1	3.2	6	31.6
