The dataset originally included as S1 Dataset was removed in consideration of possible restrictions for the public availability of the data related to the wording of the original consent form for the trial. Upon consultation with the authors’ university it has been established that the file may be publicly shared as it reports de-identified data. Please view S1 Dataset here.

The Data Availability statement for the article is revised to read: The authors have prepared a dataset that fulfills requirements in terms of anonymity and confidentiality of trial participants, and which contains only those variables which are relevant to the present study. Data are available as Supporting Information.
