Chest Ct Findings in Patients With Covid-19 Infection: A Systematic Review and Meta-Analysis

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). groundglass opacity is the foremost typical ct scan result in coronavirus disease 2019, and lung involvement is more common in bilateral and lower lung areas.
