  1. aValues are numbers (percentages) unless stated otherwise. Fisher exact probability test was applied. Bonferroni correction was used for pairwise comparisons and significant threshold was corrected as 0.05/3 = 0.017. Denoting: P-value of A vs B represents comparing the proportion of outcome between A and B
  2. P-value among three group is less than 0.001
  3. P-value of Low-risk group vs Moderate-risk group is less than 0.001
  4. P-value of Low-risk group vs High-risk group is less than 0.001
  5. P-value of Moderate-risk group vs High-risk group is less than 0.001
