A note on participation numbers

It is possible to define different definitions of participation, depending on the focus of a study. That is one of the reasons for differing participation numbers in different publications. A second reason is the possibility for participants to withdraw participation at any given moment in time, also long after data gathering took place - Later studies may therefore show a slightly lower participation rate. A third reason is quality assurance work by HUNT databank, resulting in correction of some numbers.
