实验性的:Methylphenidate
Participants were treated with methylphenidate (ranging from to 63mg) for 8 weeks.
Doses of methylphenidate were titrated depending on symptoms and adverse eff ects at the 2nd and 4th weeks of treatment.

Change From Baseline ADHD Rating Scale-IV Scores at 8 Weeks
大体时间:baseline and 8 weeks
|
Attendtion-deficit hyperactivity disorder (ADHD) Rating Scale-IV is the sum of 18 questions, ranging from 0 (no symptoms) to 54 (worst possible symptoms). Change from baseline ADHD Rating Scale-IV scores at 8 weeks was calculated as baseline minus 8 weeks. |

Clinical Global Impression-Improvement Scale at 8 Weeks
大体时间:baseline and 8 weeks
|
Clinical Global Impression-Improvement (CGI-I) scale is a one-item measure evaluating the change from the initiation of treatment on a seven-point scale: "Compared to the patient's condition at baseline [prior to medication initiation], this patient's condition is: 1=very much improved since the initiation of treatment; 2=much improved; 3=minimally improved; 4=no change from baseline (the initiation of treatment); 5=minimally worse; 6= much worse; 7=very much worse since the initiation of treatment. Clinical Global Impression-Improvement was measured at 8 weeks. |
