Criteria for inclusion or exclusion of non-consensus patient cases
| Level | Criteria |
| 1 | >60% of the score in the interval 7–9 (inclusion). |
| >60% of the scores in the interval 1–3 (exclusion). | |
| 2 | >60% of the scores >5 (inclusion). |
| >60% of the scores ≤5 (exclusion). | |
| 3 | Qualitative criteria: inclusion or exclusion of patient cases was determined based on experts’ comments and the estimated relevance of these comments to the definition. |
Patient cases that did not meet the criteria at level 1 were re-evaluated against the criteria at level 2. Finally, patient cases that could not be included or excluded at level 2 were resolved through a qualitative assessment by an independent paediatrician.21
