Grade 2A recommendation

Grade 2A recommendation
A Grade 2A recommendation is a weak recommendation, and the best action may differ depending on circumstances or patient or societal values.
Explanation:
A Grade 2 recommendation is a weak recommendation. It means "this is our suggestion, but you may want to think about it." It is unlikely that you should follow the suggested approach in all your patients, and you might reasonably choose an alternative approach. For Grade 2 recommendations, benefits and risks may be finely balanced, or the benefits and risks may be uncertain. In deciding whether to follow a Grade 2 recommendation in an individual patient, you may want to think about your patient's values and preferences or about your patient's risk aversion.
Grade A means that the best estimates of the critical benefits and risks come from consistent data from well-performed, randomized, controlled trials or overwhelming data of some other form (eg, well-executed observational studies with very large treatment effects). Further research is unlikely to have an impact on our confidence in the estimates of benefit and risk.
Recommendation grades
  1. Strong recommendation: Benefits clearly outweigh the risks and burdens (or vice versa) for most, if not all, patients
  2. Weak recommendation: Benefits and risks closely balanced and/or uncertain

Evidence grades
  1. High-quality evidence: Consistent evidence from randomized trials, or overwhelming evidence of some other form
  2. Moderate-quality evidence: Evidence from randomized trials with important limitations, or very strong evidence of some other form
  3. Low-quality evidence: Evidence from observational studies, unsystematic clinical observations, or from randomized trials with serious flaws
