Table 4.

Reasons for unsuccessful results

Reasons	Nr. of measurements	% of measurements	Nr. of participants
Not enough strength to achieve 80% threshold for GW	116	60	46
Technological problems	5	3	5
Patient was not instructible	3	2	2
Other/unknown	68	35	34

Percentages are given relative to the 192 attempted but unsuccessful measurements (GW) in the group scheduled to be measured twice daily (RM group). Participants have attempted multiple measurements and can therefore end up in multiple rows. Total number of participants with unsuccessful tests was 75
