Figure 1. Daily life physical activities in pulmonary arterial hypertension patients and control groups.

Figure 1

Mean number of daily steps (panel A), mean daily energy expended during physical activities inducing a metabolic demand >3 METs (panel B), and mean daily duration of physical activities inducing a metabolic demand >3 METs. (panel C) in healthy control subjects (CTRL; dark bars), patients with idiopathic pulmonary arterial hypertension (IPAH; grey bars), patients with limited systemic sclerosis without PAH (SSc; hatched bars), and patients with pulmonary arterial hypertension associated with limited systemic sclerosis (PAH-SSc; open bars). Values are mean ± SD. * p<0.01 vs. CTRL; § p≤0.01 vs. SSc; # p = 0.02 vs SSc. Figure legend: kcal, kilocalories; n, number.
