Topic:

  • Kronbichler et al. conducted a meta-analysis with 34 studies that included 506 asymptomatic patients with COVID-19 and reported that 62% had abnormalities visible in computed tomography (CT) scans, with ground glass opacities in the lungs most frequently observed (43%).  
  • Patients with normal CT results were younger than patients with abnormal CT findings (mean 20 years vs. 39 Years; p = 0.013).
