The dynamic changes of total CT severity score with CT follow-up times. In the severe and critical type, peak total CT severity scores occurred at the second follow-up CT (curve fitting equation: y = −0.477*x2 + 3.167*x + 6.887, in which x = number of CT examination, y = total CT severity scores; r2 = 0.137, p = 0.008). In the moderate type, there was no correlation between the total CT severity score and CT follow-up times by the SPSS curve estimation module (p = 0.426)
