Ethics approval and consent to participate

: The majority of participants (approx. 55%) were illiterate, therefore verbal consent was asked from the participants after having explained in detail about the purpose of the research and their rights to withdraw at any moment. Confidentiality was guaranteed and respondents were made aware of the fact that participation was voluntary. Participants were furthermore informed of the fact that their names would not be reproduced in any work or publication resulting from this study. Verbal consent was noted on the interview sheet. The University of Reading Ethical Committee granted ethical clearance of the present study including its consent procedure (APD B122). Professor El Garhy (CVO Egypt) granted research permission for this study.
