  2. Item scores: Each item score ranges from 1 to 4 with 1 = strongly disagree (confident that the criterion has not been fulfilled or no information was available), 2 and 3 = disagree/agree (unsure whether the criterion has been fulfilled) and 4 = strongly agree (confident that the criterion has been fulfilled) [33]
  3. Domain score calculation: Domain scores for the four AIRE instrument domains were calculated as follows: first, the two authors’ scores per item were summed up and divided by two to obtain an average rating per item; second, the average item scores were summed up per domain to obtain the domain score; and third, the domain score were standardized using the following formula: (total score per domain - minimum possible score) / (maximum possible score - minimum possible score) × 100%
  4. High methodological quality of QI set: If score ≥ 50% across all four AIRE instrument domains
