Mekori, 2017 [28]

88 (44 AN-R, 17 AN-B/P, 13 BN, 14 EDNOS-B/P)

Case control (compared patient with AN vs BN or EDNOS-B/P)

204 (SD = 91)

Weight gain admission to discharge (BMI)

Mean BMI rose significantly from admission to discharge (15.8, SD^a =1.9 to 19.8, SD = 0.7) and did not increase significantly in the BN/EDNOS group (19.8, SD = 2.1 to 21.1, SD = 1.3); F (group x time) = 88.1, p < 0.0001)

Case series

141.1 (SD = 125.7)

Weight gain admission to discharge (mean weekly weight gain and BMI)

Mean weekly weight gain was 0.43 kg/week and there was a significant rise in mean BMI admission to discharge (p < 0.001)

196.2 (SD = 68.1) for AN-R group, 178.8 (SD = 69) for AN-B/P and BN

Change in mean weight from admission to discharge (BMI)

Change in EAT −26 scores admission to discharge
