A wide variety of PROs, both generic and disease specific, are used in clinical trials around the world. This makes the comparison and synthesis of data difficult. In addition, there is often interest in producing preference-based (utility) data where an appropriate measure has not been used. One way of overcoming this problem is to estimate utility scores based on responses to another available measure using mapping techniques.
Galen Research is able conduct mapping studies to help with your clinical trial analyses. The processes involved in mapping studies can range from simple judgment-based studies to sophisticated regression-based analyses. We would be happy to discuss your needs and identify the best way to estimate the values you require.
