Black diamonds indicate ALPS (n = 18), black circles indicate DALD (n = 18), and white triangles indicate the healthy controls (HC, n = 50). The horizontal bars are the medians, the boxes indicate the interquartile range, the dashed lines indicate the 75th, and the thick line indicates the 95th percentile of the HC (Mann-Whitney U test).
