“…Of the 29 remaining studies, 18 were further excluded for similar reasons after the full text was thoroughly examined. Of these, 2 were considered as one complete study (Paniak, Toller-Lobe, Durand, & Nagy, 1998;Paniak, Toller-Lobe, Reynolds, Melink, & Nagy, 2000) because the original study had included a 1-yr follow-up published in a separate article. Therefore, the literature search yielded a total of 10 articles for inclusion in this systematic review.…”
