From: CT appearances, patterns of progression, and follow-up of COVID-19: evaluation on thin-section CT

  Initial CT (p value) Peak CT (p value) Pre-discharge CT (p value)
Initial interval 0.621 (< 0.001) 0.417 (< 0.001) 0.419 (< 0.001)
Peak interval 0.465 (< 0.001) 0.530 (< 0.001) 0.488 (< 0.001))
Pre-discharge interval 0.503 (< 0.001) 0.669 (< 0.001) 0.496 (< 0.001)
Peak-Initial interval − 0.108 (0.372) 0.153 (0.210) 0.103 (0.400)
Pre-discharge-peak interval 0.320 (0.008) 0.482 (< 0.001) 0.301 (0.006)
