Ethical Considerations
SECONDARY
This study was approved by the Tel Aviv University Ethics Committee (approval 0000154-4). This trial is registered in the National Institutes of Health Clinical Trials Registry (clinical trial NCT03736525). All participants signed the written informed consent form to take part in the study. They were informed about the purpose of the research, the expected duration of their participation, and that their participation was voluntary and they could discontinue it at any time without it causing them any harm. They were informed that the benefits of the study would be for their entire family. This should compensate them for their time. The questionnaires were not anonymous, but the participants were told that the data would be saved only on the researchers’ computers and that their ID would be removed from any publications. The informed consent allowed for the secondary analysis without having to obtain additional consent.
