↵2-150 The p value was based on the probability of a difference occurring by chance in the change in mean scores from baseline to final assessment between the intervention and control groups. Continuous variables presented as mean (SD). Categorical variables presented as percentage of patients. BP, blood pressure; n/a, not applicable.
