Ethics approval and consent to participate

: Our study protocol was reviewed and approved by the ethics committees of two participating hospitals (NEUR-2018–001, HDF-1152), and approvals from other hospitals were granted verbally by their directors. Ethical clearance letter was provided in compliance with the World Medical Association Declaration of Helsinki in 2013 []. After obtaining approvals, we contacted eligible participants, we explained all study components (importance, objectives, procedures, risks, benefits, voluntary nature, confidentiality, privacy, and right to withdraw) for a verbal consent after which a written informed consent (or their legal representatives) was necessary to participate in the study. Lastly, to maintain confidentiality, all data were coded in the questionnaire, and the questionnaire papers will be discarded once the legal retention period expired.
