Phase 2
Type of endpoint/s
Bio-equivalence
Statistical methods / analysis
Statistical analysis will be performed using commercial statistical software, with a p value of 0.05 to indicate statistical significance. Outcomes will be compared after log transformation where appropriate. Comparisons will be made using t-test and ANOVA for repeated-measures or Wilcoxon rank-signed test and Kruskall-Wallis according to the underlying distribution for continuous data and Chi-square for categorical data.
When there are baseline imbalances, logistic regression analysis will also be performed to adjust for them. Analysis will be on an intention-to-treat basis.
