Changes in peak incremental exercise data after pulmonary rehabilitation with ghrelin or placebo

	Ghrelin, n = 9	Placebo, n = 7	Treatment effect (95 % CI; p valuea)
${\dot{V}}_{{\mathrm{O}}_2}$, mL/kg/min	1.4 (0.9)	0.1 (1.4)	1.2 (0.0 to 2.5; 0.048)
${\dot{V}}_{{\mathrm{O}}_2}$, mL/min	69.3 (48.6)	8.4 (69.5)	60.9 (−2.3 to 124.1; 0.058)
Endurance time, s	56 (98)	83 (53)	−27 (−115 to 61; 0.523)
Dyspnea, Borg	−0.4 (1.3)	−1.0 (1.8)	0.6 (−1.1 to 2.2; 0.492)
Plasma LT, mg/dL	2.8 (7.9)	2.4 (12.0)	0.4 (−10.2 to 11.0; 0.937)
Plasma NA, ng/mL	−0.19 (1.32)	0.03 (0.94)	−0.22 (−1.49 to 1.05; 0.714)

Data are presented as mean (SD) unless otherwise indicated. LT plasma lactate level, NA plasma noradrenaline level; Treatment effect mean difference from pre-treatment (ghrelin minus placebo); ${\dot{V}}_{{\mathrm{O}}_2}$ oxygen uptake
