One-year follow-up CT findings in COVID-19 patients: A systematic review and meta-analysis.

ABSTRACT: Coronavirus disease 2019 (COVID-19) often causes radiological and functional pulmonary sequelae. However, evidence on 1-year follow-up of pulmonary sequelae is limited. We aimed to investigate the characteristics and time-course of pulmonary sequelae after recovery from COVID-19 through 1-year follow-up. We searched PubMed and EMBASE databases on 25 February 2022, and included studies with computed tomography (CT) findings at the 1-year follow-up. The extracted data on CT findings were analysed using a one-group meta-analysis. We further analysed the data in relation to COVID-19 severity, improvement rate and lung function. Fifteen eligible studies (N = 3134) were included. One year after COVID-19, 32.6% (95% CI 24.0-42.6, I²  = 92.9%) presented with residual CT abnormalities. G
