Definition of abbreviations: COVID-19 = coronavirus disease; CT = computed tomography; GGO = ground-glass opacities.
Data are presented as n (%), unless otherwise noted.
*
Patients without signs of radiological abnormalities at the 3-month follow-up were not scheduled for continuing visits; the percentages of abnormalities at the 6-month follow-up are based on the total number of patients at the 3-month follow-up.
†
For 45 patients, chest CT scans were available at both 3 and 6 months.
