Data analysis
SECONDARY
Demographic and clinical characteristics of both groups were described and compared using descriptive statistics and t-test, Chi-Square or Mann-Whitney U test (as appropriate) to test whether baseline differences were present. Graphical displays were used to visualise the distribution and trajectories of change in the primary and secondary outcomes over time. Propensity score matching and generalised linear modelling were used for further group comparisons, using the change scores between T1 and T0 (and T2 and T0) as the dependent variable, and using propensity score matching to manage possible baseline differences between the two groups, with the control group as the reference. Data were analysed with STATA v17 [
