The temporal change of CT scores on lung involvement. The CT scores on lung involvement in all chest CT scans (n = 215). Throughout the whole duration of COVID-19 in children, the median value of CT scores was low, with a median value of 1 or 2. It was worth noting that the CT score reached 14 in one case during 0–5 days from the onset of symptoms. The bounds of the boxes represent the 25th to the 75th percentiles; the line in the middle of the box is plotted as the median. The whiskers and the outliers are drawn according to Tukey method.
