Scientific Literature TreeMap

This data visualization makes it easy to zoom in on peer reviewed articles or clinical trial listings describing phase 2, phase 3, and phase 4 (post marketing) clinical trials with a randomized, double-blind control in multiple sclerosis. Included in this "tree map" are pointers to every article and Clinicaltrials.gov listing meeting the above criteria referenced in our Drug Development Pipeline as of June 1, 2014. The published articles describe the major results of 108 clinical trials involving 53,316 patients.

A Tree Map is a space-filling approach to showing hierarchies in which the rectangular screen space is divided into regions, and then each region is divided again for each level in the hierarchy. Tree maps have the advantage of making efficient use of space, with the potential to clearly display thousands of items on the screen simultaneously.

The regions in the tree map have an area proportional to the number of clinical trials they contain, allowing the user to identify patterns, such as which populations and which compounds are the most studied.

Click on a label or a region to zoom in. You will eventually come to links to a trial’s listing in Clinicaltrials.gov or, for a published study, its PubMed abstract. In most cases the abstract will provide a link to the full text of the study.
