Relationships between covariates and Resting Energy Expenditure in regression modeling among HIV infected subjects (p<0.0001, r2 = 0.705). Variables in bold were significantly related to REE in the model.

Relationships between covariates and Resting Energy Expenditure in regression modeling among control subjects (p<0.0001, r2 = 0.825). Variables in bold were significantly related to REE in the model.
