In our recent article [1], we did not identify several paragraphs in the background and methods that were reproduced from an article by Paulsen et al. [2]. Specifically sections of paragraphs 1 and 2 of the Background were reproduced, as well parts of the sections in the Methods, which describe scoring of classic ACF, dark ACF and tumors, histopathological analysis, and immunohistochemical analysis.
We would also like to acknowledge that what we refer to as Dark ACF in our article is the same as that which Paulsen et al. identified as Flat ACF in their article [2].
We apologise to Paulsen et al. and regret any inconvenience caused by our failure to acknowledge their work.
