CI indicates confidence interval.
†
Protected tests are performed only if the alpha for the overall test is less than .05.
‡
Test computed with 1 df because of empty cells.
§
Attention-deficit/hyperactivity disorder is reported without the criterion of onset before the age of 7 years because caretaker information is not available and self-report of symptoms before the age of 7 years is unreliable.
