Quality of evidence and strength of a recommendation.

Quality of evidence
High quality	Further research is very unlikely to change our confidence in the estimate of effect.
Moderate quality	Further research is likely to have an important impact on our confidence in the estimate of effect and may change the estimate.
Low quality	Further research is very likely to have an important impact on our confidence in the estimate of effect and is likely to change the estimate.
Very low quality	Any estimate of effect is very uncertain.
Strength of a recommendation
Strong	Most or all individuals will be best served by the recommended course of action.
Weak	Not all individuals will be best served by the recommended course of action. There is a need to consider more carefully than usual individual patient’s circumstances, preferences, and values.
