Comparison of radiographic findings between patients with D-dimer ≤ 0.7 mg/L and > 0.7 mg/L.

Radiographic finding	All	D-dimer ≤ 0.70 mg/L	D-dimer > 0.70 mg/L	P value
	(n = 76)	(n = 39)	(n = 37)
CT score	8.0 (6.0–13.0)	6.0 (4.0–9.5)	12.0 (8.0–15.0)	< 0.001
More than two lobes involvement	75 (98.7%)	38 (97.4%)	37 (100.0%)	1.000
Pleural effusion	2 (2.6%)	0 (0.0%)	2 (5.4%)	0.234
Ground-glass opacity	74 (98.7%)	38 (97.4%)	36 (100.0%)	1.000
Consolidation	55 (73.3%)	29 (74.4%)	26 (72.2%)	1.000
Reticulation and/or traction bronchiectasis	48 (64.0%)	18 (46.2%)	30 (83.3%)	0.002

Data are expressed as counts and percentage. The Pearson Chi-square or Fisher's Exact Test was used to test the difference between D-dimer groups, as appropriate.
