Adjusted* risk of a cardiovascular event (5 year), mean systolic and diastolic blood pressure at 12-month follow up in the two comparison groups (AR vs NNT)
| Outcome variable | Risk presented as | Risk presented as | ||
|---|---|---|---|---|
| Absolute Risk (AR) | Number Needed to | |||
| (n = 205) | Treat (NNT) | |||

| 5-year cardiovascular risk | 180 (87.8%) | 168 (85.7%) | Adjusted odds ratio = 1.53 | p = 0.23 |
| ≥ 10% | (95%CI 0.76,3.08) | |||
| Mean absolute 5-yr risk in | 18.3 (8.0) | 18.1 (8.0) | Adjusted difference = 0.69 | p = 0.16 |
