_aProvides the foundations that are necessary for finding and interpreting research evidence across all healthcare professions. Revised to reflect the most current changes in the field of clinical research in rehabilitation and medicine, including the growing emphasis on evidence-based practice (EBP) that has become central to all of health care and the new vocabulary that is being integrated into research and practice across disciplines. There is also a new chapter on systematic reviews and meta-analysis as well as expanded content related to clinical decision making, including likelihood ratios, pretest and posttest probabilities, minimally important change and number needed to treat. For those in the health professions, including physical therapy, occupational therapy, speech therapy, nursing, and exercise physiology.
