  1. P values comparing non-severe cases and severe cases are from χ2 test or Fisher exact test
  2. *P values comparing non-severe cases and severe cases are from Z test
  3. #P values comparing non-severe cases and severe cases are from t test. A p value of less than 0.05 was regarded as statistically significant
