a
Results from one-way ANOVA. Significant P values (alpha <0.05) indicated in bold. Weight Loss Maintainers (WLM); Normal weight controls (NC); Controls with Overweight/Obesity (OC); Physical Activity Energy Expenditure (PAEE); Total Daily Energy Expenditure (TDEE); Resting Energy Expenditure (REE).
b
n = 26 for NC and n = 25 for OC.
c
Analyzed using square root transformation, but untransformed mean (95% CI) presented.
d
Analyzed using log (base 10) transformation, but untransformed mean (95% CI) presented.
e
Analyzed using log (natural base) transformation, but untransformed mean (95% CI) presented.
