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
