Grading scoring system meta-evidence

NutriGrade score	Meta-evidence	Explanation
≥8 points	High	There is high confidence in the effect estimate, and further research probably will not change the confidence in the effect estimate.
6–7.99 points	Moderate	There is moderate confidence in the effect estimate; further research could add evidence on the confidence and may change the effect estimate.
4–5.99 points	Low	There is low confidence in the effect estimate; further research will provide important evidence on the confidence and likely change the effect estimate.
0–3.99 points	Very low	There is very low confidence in the effect estimate; meta-evidence is very limited and uncertain.
