Comparing clinical trials is an important task for medical researchers to find research opportunities, treatment strategies, and similarities. To compare sets of clinical trials is a difficult and time-consuming task due to the heterogeneity of formats within trials.

We are designing an adaptive visualization tool aimed at improving the human experience of understanding collections of related clinical trials.

We have followed a user centered design approach to ensure the usefulness and usability of the tool. We have gone through the development of low to medium fidelity mockups to communicate ideas with our users and explore alternative representations of the data.

CTeXplorer is a prototype that contains the main ideas we have explored so far, this prototype has been an excellent communication media and we are about to start the implementation of these ideas in a web-based adaptive application.

We have also exposed our prototype to preliminary evaluations from evaluators with different backgrounds. The constant input from the user and evaluations from peers and mentors give us a good indication that we are on the right path to achieve a useful design.
