Statistical analysis
Wilson’s confidence interval
REGRESSION, SECONDARY
Descriptive statistics are presented with counts and frequencies for categorical variables and with median and interquartile range (IQR) for continuous variables. Uncertainty inferences [95% confidence intervals (95% CI)] for proportions and their group differences (i.e., for the primary endpoint) are based on Wilson’s confidence interval and score interval for difference of proportions. The group differences in the primary endpoint (FPS) were analysed with a one-sided Fisher’s exact test, whereas the group difference for the secondary endpoint (TTI) was investigated with a one-sided Wilcoxon rank sum test. Predictors for the primary endpoint were investigated with a multivariable logistic regression model, where the goodness-of fit was examined using several pseudo-RAll calculations were performed using R version 4.0.2 [
