Table 2.

A set of two user patterns* was identified and calculated: percentages of regular and frequent users over the separate months and consistent for the 3-month study period

	Regular users	%	Frequent users	%
First month	45/50	90	45/50	90
Second month	41/45	91	40/45	89
Third month	36/43	84	36/43	84
Consistent over 3 months	36/43	84	34/43	79

*Patients were classified as ‘regular users’ if they completed at least 4 h of active oral appliance (OA) treatment on more than 70% of the days of the week, as defined by Kribbs et al.¹⁴ Patients were classified as ‘frequent users’ when they met the more restrictive criteria introduced by Pepin et al: mean OA use of more than 5 days per week and more than 4 h per day.²⁴
