Table1: Characteristics of included patients. Continuous variables: median(range)

All but one of the applications were performed during working hours during weekdays (Figure 1A). In 89(52%) cases, the applicator was removed outside working hours and days, including 6(4%) during the night. Figure 1B shows peaks for the removal time around 9:00h and 16:00h, which align with the start of the first (8:00h) and last (15:30h) procedure during working hours.
