Comparison of cardiopulmonary stress test (CPT) results.

CTL = healthy normal weight subjects. OB-CTL = obese subjects without a diagnosis of asthma. OB-Asthma = obese subjects with a diagnosis of asthma. OMNI = Children's OMNI scale of perceived exertion. VO2-peak = Maximum VO2 detected during the CPT. ABW = actual body weight in kg. IBW = ideal body weight in kg [male: 50+(2.3×(height in inches – 60)); female: 45+(2.3×(height in inches – 60))]. VCO2 = Maximum VCO2 detected during the CPT. RER = Respiratory Exchange Ratio. VE = Maximum minute ventilation detected during the CPT. Between-group comparison of means based on the Welch's modified version of the Students t-test. Data are presented as Mean ± SD.*Mean ± standard deviation,†Unadjusted p value,‡Bonferroni adjusted p value assuming 3 hypothesis tests.
