  • 3 Months: SMA weight change (95% CI −4.33 to –3.21); individual appointment weight change (95% CI −2.89 to –1.87); SMA systolic BP change (95% CI −7.70 to –3.39); individual appointment systolic BP change (95% CI −7.64 to –3.37); SMA diastolic BP change (95% CI −4.43 to –1.45); individual appointment diastolic BP change (95% CI −5.65 to –2.58).

  • *Data not available for all subjects. Missing 3-month values: systolic blood pressure=24, change in systolic blood pressure=24, diastolic blood pressure=24, change in blood pressure=24, weight=24, change in weight=24.

  • †Statistically significant improvement within group, p<0.05.

  • ‡For comparison between groups.

  • BP, blood pressure.
