Motor function may differentiate attention deficit hyperactivity disorder from early onset bipolar disorder

Area under the curve and suggested cut-off percentiles with and corresponding sensitivity, specificity, positive predictive value and negative predictive value in predicting ADHD-C (N = 41) versus no ADHD-C (N = 23).
C.I. = 95% confidence interval, Cut perc. = cut-off percentile, sens = sensitivity, Spec = specificity, PPV = positive predictive value, NPV = negative predictive value***p < 0.01; **p < 0.03, *p < 0.05 (null hypothesis: true area = 0.5).
