the interval between onset of symptoms and establishing the diagnosis of endometriosis on a 9-point Likert scale ranging from 1 (extremely irrelevant) to 9 (extremely relevant). An example of the score sheet is provided in Figure 1. In order to support discrimination between interventions with a high Likert score, the panel members were subsequently asked to compose a personal top-5 ranking of the interventions they considered the most relevant. Participants were given the opportunity to comment on their appraisal of the interventions and to add suggestions for additional interventions.
To what extent is the following intervention relevant in reducing the time between onset of symptoms and establishing the diagnosis of endometriosis?
You can move the slider by dragging it in the desired position. The associated score will become visible during the movement of the slider. The higher the score, the more relevant the intervention.

Data analysis of the first round
The results of the first round were analysed using predefined criteria based on the literature.22,24,31 Each intervention was scored on three criteria: 1) a median rating of 8 or higher on the Likert scale, 2) panel agreement, and 3) a high ranking score. Panel agreement was based on the distribution of scores for each intervention and was confirmed if ≥75% of panel members’ individual scores were in the highest tertile of the Likert scale (7-8-9). Interventions should have at least 15% of the maximum ranking score to fulfil the third criterion. Ranking points were appointed to each top-5 ranking position; a number 1 position was appointed 5 points, number 2 position was appointed 4 points and so on until a number 5 position which was appointed 1 point. The sum of the received ranking points was converted into a percentage of the maximum ranking score. The maximum ranking score is defined as the
