Correlation between BICAMS and ICA for (a) MS patients and (b) healthy controls. Each scatter plot shows the ICA score (y axis) vs. one of the tests in BICAMS (x axis). Each blue dot indicates an individual; the blue dashed lines are results of linear regression, fitting a linear line to the data in each plot. For each plot, the Pearson correlation between ICA and a BICAMS test is written in the bottom-right corner. If we combine the data from MS patients and healthy controls (n = 174 total), the ICA vs. BICAMS correlations will be the following: correlation with SDMT: 0.82 (p < 10–11); BVMT-R: 0.60 (p < 10–8); CVLT-II: 0.71 (p < 10–10). ICA: Integrated Cognitive Assessment; SDMT: Symbol Digit Modalities Test; BVMTR: Brief Visual Memory Test–Revised; CVLT-II: California Verbal Learning Test -2nd edition. Stars (*) show significant correlation at p < 10–8
