Although there was a considerable variation in ULK1 gene expression, plotting the data without an outlier confirmed that RA patients exhibited significantly upregulated ULK1 gene expression (p = 0.01) at baseline (Supplementary Material, Figure  4, available online at http://dx.doi.org/10.1155/2016/4963950). Here, ULK1 is linked to rheumatoid arthritis.
