2.2. Study Design
This is a prospective, randomized, double-blind, interventional study. The investigators used a random number generator to divide the enrolled patients into two groups: the control group (dietitian-prescribed diet formula based on clinical judgment without knowledge of BIA data) and the intervention group (BIA data disclosed to the dietitian for reference). The registered dietitians in charge of the patients in the intervention group were encouraged to use BIA data for adjusting the diet formula according to the patient’s body composition variables. Patients and other medical team members caring for the enrolled patients were blinded to the randomization. The study design was approved by the Institutional Review Board of Chang Gung Memorial Hospital without any conflict of interest (Approval No: 201901875A3C501).
