In the article cited here,1 which published in the January 2019 issue of the journal, the author has noted an error in patient 6-minute walk test (6MWT) data. As published, the text expresses 6MWT data in units of feet, but the correct unit for the data presented should have been meters. Thus, in the Results section, the text should have read, "Patients under the TR model had a greater increase in 6MWT distance (82.1 +/- 57.5 m) than those under the OG model (57.2 +/- 59.8 m), and results were consistent when accounting for age, race, and sex."

This change also affects 2 rows within Table 1, changing the unit for 6MWT from ft to m. The corrected version of the table is presented below.
