Analysis of the procedural elements
Only guidelines with published comments were included in the study
(n=87). The key dates of the guidelines were listed as end date of the
consultation and adoption date of the guideline. The time elapsed
between the two dates was measured as days.
Question and answer documents were not assigned an author and they are
missing from the subgroup analysis comparing the WPs. Only the WPs that
authored at least three guidelines were included in the subgroup
analysis.
