But osteopathic organizations prefer to retain a separate identity and have exaggerated the minor differences between osteopathy and medicine in their marketing. According to a 1987 AOA brochure, for example: (a) osteopathy is the only branch of mainstream medicine that follows the Hippocratic approach, (b) the body's musculoskeletal system is central to the patient's well-being, and (c) OMT is a proven technique for many hands-on diagnoses and often can provide an alternative to drugs and surgery .

High-impact journals are those considered to be highly influential in their respective fields.
The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information.
