Study cohort. *World Health Organization (WHO) group 1 pulmonary hypertension (PH) means pulmonary arterial hypertension (PAH). **WHO group 2 PH means left heart disease-associated PH. This group was excluded for validating the performance of all models for PAH but included in validating the performance for PH. ***WHO group 3 PH means lung disease/hypoxia-associated PH. This group was excluded for validating the performance of all models for PAH but included in validating the performance for precapillary PH and PH. ASIG, Australian Scleroderma Interest Group; ESC/ERS, European Society of Cardiology/European Respiratory Society; FVC, forced vital capacity (percentage predicted); RHC, right heart catheterization; SSc, systemic sclerosis; TRV, tricuspid regurgitant velocity.
