Table 2.
Type and distribution of lung lesions by using a cut-off of 5 days from symptoms onset and a cut-off of 60 years old. Interstitial pattern and alveolar opacities are statistically higher in patients with symptom onset >5 days and in older patients. Radiological findings are typically bilateral, subpleural and involving more than one lung portion with a statistically significant difference.
