None of the variables differed significantly between groups; p-value of <0.05 considered significant. + Post-hoc analysis of VBSc score change over time for primary outcome was conducted using the Bayesian multinomial ordinal model. Good convergence was obtained after merging patients into five groups. Bayesian analysis with a neutral prior indicated that the 5th centile of the posterior odds ratio (treatment vs control) was 1.25. Thus, there was 95% chance that the treatment group did better than the control.
