Distribution of N blocks of non-wear over the full observation period among the 1241 participants with at least one non-wear event. Note % of non-wear per person-day (a) was calculated among the 219 person-days with at least one non-wear episode and less than 1/3 of non-wear during the day period and % of non-wear per person-night (b) was calculated among the 1490 person-nights with at least one non-wear episode and less than 1/3 of non-wear during the night period
