Erratum to: Health disparities and treatment approaches in portopulmonary hypertension and idiopathic pulmonary arterial hypertension: an analysis of the Pulmonary Hypertension Association Registry (Pulmonary Circulation, (2021), 11, 3, (1-10), 10.1177/20458940211020913)

Dear Editors, The authors would like to make a correction to the article, Health disparities and treatment approaches in portopulmonary hypertension and idiopathic pulmonary arterial hypertension: An analysis of the Pulmonary Hypertension Association Registry, published in Pulmonary Circulation in May 2021.¹ The authors were made aware of a central coding error in the data set for the Pulmonary Hypertension Association Registry which impacted the calculation of the Short-Form 12 physical component summary score and mental component summary scores, incorrectly labeled as SF-36 in the manuscript table. We have repeated the analysis using the corrected data set. The repeat analysis with the corrected data set affected the results reported in Table 2 as detailed below but did not affect the conclusions. Please note that the sample size is different in the new data set due to subsequent subject withdrawal from the study. (Table presented.) The text of the manuscript, including the results, discussion, and conclusions, were not affected and do not need to be modified. We sincerely apologize for the error. Sincerely, Hilary M. DuBrock MD on behalf of all co-authors.
