- Top three brainstem PCs are correlated to neuropsychometric measurements (clinical severity, n = 70; clinical neurological severity, n = 70; clinical ADD/ADHD diagnosis, n = 50; IQ, n = 61; and Attention Comparison Score, n = 68). The correlation matrix combines the Pearson correlation and Spearman correlation (italicized) results. Abbreviations used in the table: Clin. Sev. = clinical NF1 severity, Neuro. Sev. = clinical neurological severity, ADD/ADHD = clinical Attention deficit hyperactivity disorder severity, IQ = intelligence quotient, ACS = Attention Comparison Score, and PC = principal component
