Although the efficacy of combined treatment targeting pulmonary arterial hypertension (PAH) has been suggested to be preferable, the comparative efficacy of combination therapy versus monotherapy in connective tissue disease (CTD)-associated PAH (CTD-PAH) remains undetermined. We performed a meta-analysis regarding this topic. ⋯ Combination therapy targeting PAH may confer preferable therapeutic efficacy compared with monotherapy in patients with CTD-PAH as evidenced by a more remarkable reduction in the risk of clinical worsening and a probable improvement of exercise capacity in these patients.
