A health service offers a lifestyle programme to adults with a high risk of cardiovascular disease. It is considering adding a medicine to the programme.
The table shows expected outcomes over five years for comparable patients.

| Lifestyle programme only | 64 | 0 |
| Lifestyle programme and medicine | 40 | 8 |
The combined treatment will be offered to 18 000 patients. It is expected that 75% of these patients will take the medicine regularly.
