In the article titled “Changes in Retinal Thickness and Brain Volume during 6.8-Year Escalating Therapy for Multiple Sclerosis” [1], incorrect versions of Figures 1(a) and 1(b) were published due to an error in the production process. Specifically, “baseline” and “high-efficacy DMT” on the -axis are incorrectly labelled. In addition, the -axis labels are displaced from the corresponding bar chart columns. The correct figures are shown below.
