Ethical consideration
The study was approved by the institutional review board (IRB) at College of Medicine, KSU (project number: E-17-2419). Written informed consent was obtained on an individual basis. However, an amendment for acquiring informed consent electronically was approved by the IRB office due to the COVID-19 outbreak. Data were electronic in nature and were kept on a private computer, which had no public access and was password protected. The privacy of the research participants was protected, as was the confidentiality of their personal information. The first author (AA) had access to information that identifies individual participants during and after data collection. The consent process and the study data were monitored by the IRB’s compliance office.
