Ethics approval and consent to participate
: The study was reviewed and approved by the Dr. Ram Manohar Lohiya Hospital Institutional Review Board. Consent forms were read out to participants and required their signature. Names of participants were not requested, instead a unique identification number was assigned to each of them. Participants were ensured complete confidentiality, and were given the choice of voluntarily withdrawing from the study.
: We did not require consent for publication as we did not use individual data in the form of images, videos or voice recordings. Voice recordings were transcribed immediately and the recordings destroyed after 1 year of the study so that no identifying information can remain in the raw data.
: The authors declare that they have no competing interests.
: Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations.
