In this work, we evaluated computed tomography (CT) results of the chest in patients with COVID-19 pneumonia. Preliminary articles were searched in the scientific databases PubMed, MEDLINE, Embase, EBSCO between 2019 to 2021. Fixed-effect model for meta-analysis using the inverse-variance method calculates effect size with 95% confidence interval (CI). Data analysis was performed using STATA software version 16. Overall effect size of Ground glass opacities (GGO) in patients with coronavirus disease 2019 (COVID-19) was 2.30 (ES, 95% CI 1.56, 3.3). Ground-glass opacity was a typical finding in COVID-19 pneumonia on CT; its incidence was about 80%. Abnormal CT in patients with COVID-19 was 2.69 (ES, 95% CI 2.52, 2.87). Ground-glass opacity is the foremost typical CT scan result in coronavirus disease 2019, and lung involvement is more common in bilateral and lower lung areas.
