Classification of median and disagreement of experts on different scenarios.

Median	Disagreement	Classification
7–9	No	Appropriate with agreement
7–9	Yes	Appropriate but with disagreement
4–6	Not applicable	Uncertain
1–3	Not applicable	Not appropriate

The mean and disagreement were classified into three levels of appropriateness (appropriate: between ‘7’ and ‘9’, without disagreement; uncertain: between ‘4’ and ‘6’ or any median with disagreement; inappropriate: between ‘1’ and ‘3’ with agreement).
