^†Values considered as average % of daily wear time. VO₂, oxygen consumption; RQ, respiratory quotient; EE_FOX/FFM, energy derived from fat oxidation, expressed per unit fat-free mass; FOX%, fat oxidation (% of total energy metabolic sources); GLC, glucose concentration in capillary blood (the load value is referred to the peak concentration measured either 15 or 30 min after the meal). ΔGLC, changes in glucose concentration in capillary blood, after the glucose-rich test meal. Significance of correlation (2-tailed): * at the 0.05 level, ** at the 0.01 level.
