Statistical analyses
REGRESSION
As descriptive analyses, medians and interquartile ranges were calculated for the continuous variables and percentages for the categorical variables, overall and by study group. We first described the prevalence of responses for each question and original categories on the Likert scale, in the total sample, and by study group. Then, we used log-binomial regression models with robust variance errors to assess outcome differences across study groups unadjusted and adjusted for covariates. We determined statistically significant differences between groups if the confidence intervals did not cross the null value. However, as recommended, we also discussed results that provide a broader picture of the results, even though not statistically significant. In the same sense, we did not present p-values given their dichotomous use into “significant” and no “significant”, which is no longer recommended [
