Rapid Evaluation of Innovative Intervention Components to Maximize the Health Benefits of Behavioral Obesity Treatment Delivered Online: An Application of Multiphase Optimization Strategy

Weight was measured at the research center by the research team, or measured by the participant at home and sent to the research team with with documentation of the value reported (e.g., a photograph from a home scale showing the weight).

A change between two time points is reported. The value of this outcome was calculated using: [(baseline weight - month 12 weight) ÷ baseline weight] × 100. Estimated mean change was obtained from a linear mixed models analysis of variance. Data from all randomized participants were included in the model (ITT analysis).

This outcome measure is reported as an additional effect beyond that of Outcome Measure 1 (each intervention component has it's own weight loss effect that is above and beyond the weight change calculated in the Outcome Measure 1 analyses).

Weight was measured at the research center by the research team, or measured by the participant at home and sent to the research team with with documentation of the value reported (e.g., a photograph from a home scale showing the weight).

Weight loss was calculated using: [(baseline weight - month 12 weight) ÷ baseline weight] × 100.

The estimated proportion of participants achieving a weight loss of ≥ 5% of their Baseline body weight was obtained from a generalized linear mixed models analysis of variance to account for missing data. All randomized participants were utilized in the model (ITT analysis).

Weight loss was calculated using: [(baseline weight - month 12 weight) ÷ baseline weight] × 100.

Estimated proportions of participants with weight loss of ≥ 5% of initial body weight at Month 12 were obtained from a generalized linear mixed models analysis of variance to account for missing data. All randomized participants were utilized in the model (ITT analysis).
