Figure 1From: Aerobic capacity and disease activity in children, adolescents and young adults with juvenile idiopathic arthritis (JIA)Aerobic capacity (expressed as median Z-score of VO 2peak and VO 2peak /kg) in relation to age in adolescents and young adults with JIA. Z scores are compared to age and sex related healthy controls (p-values <0.01). Abbreviations: Z-score: standard deviation of the individual patient compared with values from age- and sex- related historical Dutch controls(37); VO2peak abs: highest oxygen uptake in liters of oxygen per minute (l/min) during maximum exercise test in l/min; VO2peak/kgl : highest oxygen uptake in milliliters of oxygen per kilogram of bodyweight per minute (ml/min/kg) during maximum exercise.Back to article page
