HRCT score and peak day in COVID-19 patients with pneumonia or severe pneumonia. (A) Graph showing temporal HRCT score changes in 99 COVID-19 patients with pneumonia (blue) or severe pneumonia (red). (B) Graph showing temporal HRCT score changes in 11 pneumonia patients with follow-up CT scans. In (A,B), each line represents temporal radiographic changes in one COVID-19 patient. Each dot represents a HRCT scan. (C) Graphs showing the distributions of HRCT scores (peak) (p = 3.6 × 10−12) in COVID-19 patients with pneumonia or severe pneumonia. ****p < 0.0001. (C) Graphs showing the distributions of Days to Peak (Peak Day) (p = 0.048) in COVID-19 patients with pneumonia or severe pneumonia. Peak days are the time from admission that it takes for the maximal chest HRCT abnormalities to develop. *p < 0.05.
