Statistical analysis
All statistical analyses were performed using the IBM SPSS version 26.
Differences in characteristics of the patients between the two groups,
that is, the pre-screening and post-screening cohorts were compared
using the independent sample t-test for the continuous variables and the
Chi2 test for the categorical variables. Multivariate
Analysis of Covariances (MANCOVA) was used to determine if there was an
association between any of the demographics and the perceived ratings of
the opinion statements.
