GRADE system (Grading of Recommendations Assessment, Development and Evaluation)

The GRADE system is a method used by healthcare professionals to evaluate how strong and reliable the evidence is for different medical treatments or recommendations. It looks at factors like study quality, consistency of results, and how directly the evidence applies to patients. Based on this, it classifies the confidence in the evidence as high, moderate, low, or very low. This helps both doctors and patients understand how much trust can be placed in medical advice, guiding better-informed decisions about care options.
