Definition of Strength of Recommendation
Symbol | Strength of recommendation | Description |
---|---|---|
A | Strong recommendation | Considering the benefits and harms, level of evidence, values and preference, as well as resources of the intervention/examination, it is strongly recommended in most clinical situations. |
B | Conditional recommendation | Considering that the use of the intervention/examination may vary depending on the clinical situations or values of patients/society, selective use or conditional selection of the intervention/examination is recommended. |
C | Not recommended | The harm of the intervention/examination may outweigh the benefits and considering the clinical situations or values of patients/society, the use of the intervention/examination is not recommended. |
I | Inconclusive | Considering the benefit and harm, level of evidence, values and preference, as well as resources required for the intervention/examination, the level of evidence is too low, the weighing of the benefit/harm is seriously indecisive, or the variability is large. Therefore, the use of the intervention/examination is not determined. |
