Data collection
Before the actual data collection, data collectors were trained on how
to collect the necessary data. A single-day training was given to the
research staff on the research protocol. A pre-test was done, and three
of the investigators carried out the data collection.
The study was approved by the ethics review committee of the school of
pharmacy, University of Gondar. Informed consent was sought from the
study participants prior to data collection and confidentiality and
anonymity of subjects were maintained by not recording identifying
details, such as name or any other personal identifiers.
