Linear regression analysis - dependent variable VO_2peak/kg (ml/min/kg), VO_2peak (ml/min) or Max. load (all logarithmized), independent variable pGDM/control status.

<p>BMI: body mass index; CI: confidence interval; Max. load: maximum workload in cardiopulmonary exercise testing; VO_2peak: peak oxygen uptake; VO_2peak/kg: peak oxygen uptake per body mass.</p

Spearman correlation coefficients for leptin and selected other variables.

<p>BMI: body mass index; TG: triglycerides; HDL: HDL cholesterol (mg/dl); ISI: insulin sensitivity index; load: maximum workload in cardiopulmonary exercise testing; VO2: peak oxygen uptake; VO2/kg: peak oxygen uptake per whole body mass; WC: waist circumference (cm); p-value <0.0001 for all, except for leptin with VO2 (p = 0.015).</p

Characteristics of the study sample.

<p>BIA: bioelectrical impedance analysis; BMI: body mass index; ISI: insulin sensitivity index; Max. load: maximum workload in cardiopulmonary exercise testing; MRI: magnetic resonance imaging; VO_2peak: peak oxygen uptake; VO_2peak/kg: peak oxygen uptake per body mass.</p

Linear regression analysis - dependent variable leptin (logarithmized).

<p>BMI: body mass index; CI: confidence interval; pGDM: previous gestational diabetes; Max. load: maximum workload in cardiopulmonary exercise testing; VO_2peak: peak oxygen uptake; VO_2peak/kg: peak oxygen uptake per body mass.</p
