| Grade . | Quality level . | Definition . |
|---|---|---|
| A | High | We are confident that the true effects lie close to that of the estimates of the effect |
| B | Moderate | The true effects are likely to be close to the estimates of the effects, but there is a possibility that they are substantially different |
| C | Low | The true effects might be substantially different from the estimates of the effects |
| D | Very low | The estimates are very uncertain and often will be far from the truth |
