a
Each estimate is a summary estimate of five repeated analyses for five imputed dataset. Each analysis used a random effect model with random intercept for individual, adjusted for age, race, education, job, marital status, medical history, smoking status, previous participation of formal dieting program and treatment assignment.
b
P values are derived from a random growth model with random intercept for individual allowing random slope for time and time-squared.
Adjustment factors are same as above. Time in linear scale was used.
