Table 2. Linear regression analysis - dependent variable VO2peak/kg (ml/min/kg), VO2peak (ml/min) or Max. load (all logarithmized), independent variable pGDM/control status.
BMI: body mass index; CI: confidence interval; Max. load: maximum workload in cardiopulmonary exercise testing; VO2peak: peak oxygen uptake; VO2peak/kg: peak oxygen uptake per body mass.
