Snippet: Missing data will be checked and imputed using the median for continuous variables or the most common category value for categorical variables to preserve power, if there is <10% missing data. Otherwise, multiple imputation techniques will be used. The Shapiro-Wilk test will be used to check data for normality. Student's t-test and Mann-Whitney U test will be used for group comparisons of continuous parametric and nonparametric variables at basel.....
Document: Missing data will be checked and imputed using the median for continuous variables or the most common category value for categorical variables to preserve power, if there is <10% missing data. Otherwise, multiple imputation techniques will be used. The Shapiro-Wilk test will be used to check data for normality. Student's t-test and Mann-Whitney U test will be used for group comparisons of continuous parametric and nonparametric variables at baseline. χ 2 or Fisher's exact tests will be used for group comparison of categorical data at baseline.
