Erratum: Prediction of Health-related Quality of Life and Hospitalization in Pulmonary Arterial Hypertension: The Pulmonary Hypertension Association Registry

The letter by Min and colleagues (1), published in the March 15, 2021 issue of the Journal, relies in part upon data provided by the Pulmonary Hypertension Association Registry (PHAR). After the article had been published, the PHAR notified investigators who had used their data that an error had occurred when they had calculated the composite scores of the Medical Outcome Study Short Form-12 (SF-12) physical and mental components. The distributed datasets did not accurately reflect scores reported by participants: the coding error failed to reverse code responses for four of the twelve SF-12 questions.

Once the error was discovered by the PHAR team, they notified investigators who had used their data and provided updated corrected datasets. Min and colleagues then extracted the new SF-12 physical and mental scores from the corrected dataset and performed the analysis again. The authors informed the Journal that although there were small changes in the effect estimates, the article’s conclusions have not changed. However, corrections have been made to the text of the letter, the table, and the figure. Two new panels (1B and 1C) have been added to the figure: panel 1A remains unchanged; the former panel 1B is unchanged but has been relabeled panel 1D.

For the convenience of our readers, the Journal is replacing the online version of the article with a corrected version. In addition, a document showing all the changes to the data will be posted as an online supplement to the original article.
