Unfortunately, after publication of this article  it was noticed that the author list was incorrectly captured during the production process. The original author list contained the group “Rheumatic Diseases Portuguese Register” however this was included erroneously and instead should only be listed as the affiliation for Helene Canhão. The correct author list can be seen above and the original article has been updated to reflect this change.
