Authors' recommendations: In this research, an indirect comparison methodology used in the context of Health Technology Assessment (HTA). As an example of HTA using indirect comparison, the efficacy of Atomoxetine and Methylphenidate in Adults Attention Deficit Hyperactivity Disorder(ADHD): A Rapid Review conducted by full term for NECA in 2012 was selected as an exemplar. Indirect comparison was performed using ITC program (version 1.0). The treatment effect of methylphenidate showed more significance in reducing ADHD symptoms compared to atomoxetine. The significant difference was readily evident when comparing OROS methylphenidate and atomoxetine. Such an effective difference has been proven through research involving children and adolescents (Hanwlla et al. 2011). Therefore, although there are not enough appropriate head-to-head trials for adult ADHD patients to compare the treatment effects of the two drugs, indirect comparison using a common comparator was effective to compare each treatment effect, and was proven by comparing the results to prior studies conducted with children and adolescents. There are numerous limitations to the use of indirect comparison for HTA, but it can be considered when head-to-head trials are absent. Furthermore, treatment effects resulting from indirect comparison can be used with direct comparison and different research methods to evaluate the significance of treatment effectiveness in clinical usage.
