Note: Mean values reflect statistical adjustments for participant age, sex, marital status, educational attainment, and race/ethnicity. Changes in outcomes observed for participants who participated in 7-11 sessions were greater than changes observed for participants who participated in ≤6 sessions.
↵a Significant change from baseline at the P < .025 for body composition measures (Bonferroni-corrected nominal P value) and at the q =.05 (false-discovery rate) correction for multiplicity of hypothesis testing for the 3 satiety measures.
↵b Group-by-time interaction (group difference in differences from baseline to 12 months follow-up).
↵c Waist circumference not corrected for variation in measurement over clothing.
↵d Waist circumference corrected for variation in measurement over clothing.
