Definition of strength of recommendation
| Sign | Strength of recommendation | Definition |
|---|---|---|
| A | Strong recommendation | Strong recommendation is made for most clinical situations when the benefits of the intervention/test outweigh the risks, considering the level of evidence, values and preferences, and resources. |
| B | Conditional recommendation | The use of this intervention/test may vary depending on the clinical situation or patient/social values, so it is recommended to use it selectively or conditionally. |
| C | Not recommendation | The potential harms of this intervention/test may be greater than the benefits, and considering the clinical situation or patient/social values, it is recommended not to implement it. |
| D | Inconclusive | When considering the benefits and harms of this intervention/test, the level of evidence is too low, and the balance between benefits and harms is seriously uncertain or there is significant variability. Therefore, the decision to implement the intervention is not determined. |
