Kahr Rasmussen N, Berg B, Christiansen ASL, et al. Patient Prefer Adherence. 2024;18:1713—1727. Page 1719, Table 4, Range column, Total row under the Time to prepare and inject section, the text “0 min 29s–4 min 7s” should read “0 min 29s–4 min 3s”. The correct table is as follows. Table 4 Measurements of training time, time to administer an injection, and the correct execution of the injection Page 1719, Ease-of-Learning to Use and Ease-of-Use of the Concizumab Pen-Injector section, second line, the text “(n=78, 97%)” should read “(n=78, 98%)”. Figure 3 on page 1720 is incorrect. The correct Figure 3 is as follows. Figure 3 The ease of learning and ease of use of the pen-injector as assessed using the HDHPA questionnaire. (A) Responses from participants to HDHPA question 1 on factors associated with ease of handling and use of concizumab pen-injector. Participants were asked to select the response that most closely represented how they felt using the pen-injector. (B) Responses from participants to HDHPA question 2 on overall difficulty or ease of use of the concizumab pen-injector. Responses were assessed on a 5-point scale ranging from very difficult to very easy. Responses for very difficult and difficult were combined to represent negative results and the responses easy and very easy were combined to represent positive results. Data are presented as number of responses with percentages % (n). Page 1722, Discussion section, eighth line, the text “(97%)” should read “(98%)”. The authors apologize for these oversights.
