*7-day accelerometry was assigned to 50% of all participants who received only the Level 1 examination programme, but was offered more frequently at some study centres
**56,971 participants received the Level 2 programme
***Each study centre selected one of three modules (1 of 3 exam system) to be carried out in all Level 2 participants, while the other two modules are only performed in a subgroup of 100 participants. The angle chair and hand examinations counted as one 1 of 3 examination module. Some study centres chose 2 out of 3 modules and carried out each module on one-half of all Level 2 participants
