9.11 Table C.13 Anorexia data Ben-Tovim et al. (1979) report a case-control study to test hypothesis that anorexic people tend to overestimate their true waist measurements.Eight anorexic women were identified from a hospital in-patient unit and compared with 11 non-anorexic adolescent schoolgirls. The outcome variable used to compare cases and controls was the body perception index, BPI = 100 * (perceived waistwidth)/ (true waist width) The data collected were as follows: Subject number Waist width (cm) Cases True Perceived BPI...
