Derivation of study population for patients with pulmonary arterial hypertension and sepsis or septic shock. This figure demonstrates how the study population of patients with PAH and SSS was selected from the NRD. A total of 1,134 patients with PAH and SSS were identified over years 2016–2017 after applying the exclusion criteria. Five patients had data missing for the propensity matched variables, and were, subsequently, excluded from the final cohort for comparison. PAH = Pulmonary arterial hypertension. SSS = Sepsis or Septic Shock
