Hypothetical example of how criteria are rated on RAND scales of appropriateness and necessity
| Patient with angina is still symptomatic on two drug therapy | Appropriateness of offering third drug | Necessity to offer third drug |

| 2. Offered referral to a cardiologist | 1 2 3 4 5 6 7 8 9 | 1 2 3 4 5 6 7 8 9 |
