To reply on this comment and to provide readers with more precise data we made some changes in two sections. In the subsection “Sample size” of the section “Materials and methods” we emphasized that “students from 16 faculties of the University of Banja Luka were participants in our study”. In section “Results” we have added a new sentence that “Majority of study participants were medical students (41.4%) and the rest were students from other faculties (58.6%).” Comment 3.
Study sample - please provide more precise data on population (faculties at the university and its share in the total sample of recruited subjects)
