Abstract: DECIDE-Diet trial was taken as a case to introduce the methods of blinding and blinding assessment for feeding trials, report the details of blinding, conduct a blinding survey and calculate Jame's BI and Bang's BI. Jame's BI was 0.683 (95% CI: 0.593~0.772). The Bang's BI for the intervention group was 0.340 (95% CI: 0.199~0.481), and for the control group was 0.086 (95% CI: -0.060~0.231). The blinding of the DECIDE)-Diet was generally successful, but the intervention group may infer their group to a certain extent. Feeding trials should report the details of blinding and consider blinding assessment.
