Asterisks () denote p<0.05 post-hoc 𝝌2-test compared to Low Risk cohort.
Categoric data are shown as number (%) and continuous data as median (interquartile range)
Univariate comparisons for continuous variables made with Student’s t-test; comparisons for categorical variables made using Pearson’s chi-squared test or Fisher’s exact test, as appropriate.
