Fig. 3. Radiological characteristics and laboratory indicators detected in asymptomatic, presymptomatic, and symptomatic patients. (A) The percentages of typical characteristics in chest CT imaging. The vertical axis indicates the percentages of typical characteristics. The horizontal axis represents the typical characteristics of the lung. Red, orange and blue represent the asymptomatic, presymptomatic, and symptomatic group, respectively. (B) The abnormal rate of organs, including heart, liver, and kidney (> normal range). The vertical axis indicates the rate of abnormal. (C) The abnormal rate of organs, including heart, liver, and kidney (>2-fold normal range). (D) The values of laboratory indicators after admission. The vertical axis indicates the values of laboratory indicators. TheP -value was calculated using the Wilcoxon’s rank-sum test and shown at the top of each panel. Boxplots represent the 25th and 75th percentiles, with midlines indicating the median values. *** representsP -value < 0.001. ** represents P -value < 0.01. * represents P -value < 0.05. NS. represents P -value > 0.05.
