There are strengths and limitations to our study. Although there may have been some self-selection bias in our study, the recruitment through the national CMyLife digital patient platform did allow for a substantial and geographically nationwide spread of participants, also in a time when many patients isolated themselves and hospital visits were limited when possible. Also, our study was performed prospectively, and included a control group. Furthermore, our questionnaires focused on patients’ perceptions, offering insights in the substantial level of anxiety in this patient group. However, the number of SARS-CoV2 tested subjects was low, limiting statistical power.
