*) cut-off values determined by the large group
The highest cut off level yielding a sensitivity ≥ 0.90 (≥ 0.95 for ASD and AD/HD) and the lowest yielding a specificity ≥ 0.90 (≥ 0.95 for ASD and AD/HD), with the actual sensitivity and specificity first in the clinical and control groups, then in the larger group including both index groups.
