We performed a comprehensive database search for abstracts published in English from 1960 to March 15, 2015, in Pubmed, PsycINFO, Scopus, and Clinical Trials databases. Search strategies combined controlled vocabulary terms (MeSH, Thesaurus) with keywords and phrases for the following concepts: refeeding, weight restoration, hypophosphatemia, and anorexia nervosa. Exclusion terms were: neoplasm(s) and cancer(s) and tumor(s). References were exported to Endnote (version X7), and duplicates were removed using Author, Year, Title, and Reference Type as the comparison criteria.
