ANOREXIA
To calculate the sample size, according to the study design, Cochran’s sample size formula was used considering a type I error of 5% (α = 0.05) and SD power of 80% (β = 0.20) for all outcomes, such as pain, sleep quality, anorexia, and fatigue. Mean ± SD was calculated for the intervention and control groups for all variables. The largest calculated sample size was for fatigue. Considering fatigue as the primary outcome in this study and 20% dropout, a sample size of 37 participants was determined for each study group.
