Diffusion lung capacity for carbon monoxide correlates with HRCT findings in patients with diffuse parenchymal lung disease

The Egyptian Journal of Bronchology

Table 8 Correlation between degree of diffusion lung capacity for carbon monoxide and degree of total Warrick’s score

	DLCO-SB			Test value	P value	Sig.
	Mild	Moderate	Severe
	No. = 24	No. = 27	No. = 38
Warrick’s total score
Mild	1 (4.2%)	1 (3.7%)	0 (0.0%)	30.343	0.001	HS
Moderate	19 (79.2%)	12 (44.4%)	5 (13.2%)
Severe	4 (16.7%)	14 (51.9%)	33 (86.8%)
