After publication of the original article [1], the authors have notified us of an error in language used in the text:
-
The first sentence of the 6th paragraph under the Methods sections should read “Training was completed for each individual patient.”
-
The first sentence of the 3rd paragraph under Training of patients and site staff should read: “The site staff underwent face-to-face training and hands-on experience with the devices at investigator meetings or online training modules and took 2 hours to complete on average.”
The phrase “took 2 hours to complete on average” was moved from the first sentence to the second one.
