Note: for continuous variables, all values were expressed as mean ± SD and Student’s -tests were performed to compare means between the groups. For categorical variables, all values were expressed as (%) and comparisons were performed with Chi-square tests. PAH: pulmonary arterial hypertension; 6MWD: 6-minute walk distance; WHO: World Health Organization; ET: endothelin; COPD: chronic obstructive pulmonary disease.
