From: A single-center, retrospective study of COVID-19 features in children: a descriptive investigation

Changes in CT images during treatment
Completely absorbed1.0
Partially absorbed0.56 (0.25, 1.28), 0.168
No change0.11 (0.01, Inf)c
Worse0.34 (0.10, 1.13), 0.08
  1. aUsing the time-vary Cox regression method, p < 0.05 was considered to indicate statistically significant difference
  2. bAdjusted for gender, age, PCR positive and CT positive
  3. cThis model failed when analyzing “no change in CT image” due to the small sample
