The journal “Asian Pacific Journal of Cancer Prevention” has been excluded from the SCI since 2015, so its impact factor and classification in 2014 were used here; no statistical analysis on journals’ quartile in category was separately performed because of differences in the classification criteria of journals in various fields, where many disciplines, including cancer, oral cavity, and epidemics, are involved.
