^* Asterisks indicate the influence of the factor on the linear coefficient of the weight loss trajectory (* week). None of the factors significantly influenced the quadratic coefficient of the weight loss curve at Month 3. Factor coefficients are not directly comparable due to differences in scoring ranges.
