*Systolic and diastolic blood pressure estimates were based on a longitudinal data model with an unstructured covariance matrix
Negative differences reflect improvement (i.e. decreased blood pressure) compared to usual care, and positive differences reflect worsening (i.e. increased blood pressure) compared to usual care
The model-estimated systolic blood pressure correlation between time points ranged from 0.26 to 0.41. The estimated diastolic blood pressure correlation between time points ranged from 0.41 to 0.53
