The most populous three states in the US—California, Texas and New York—were the only states last year to launch more than 1,000 human clinical trials each. That's not surprising, given the millions of people inhabiting each of these states. But when you take into account the enormity of each region and look at the number of clinical trials per capita, the Golden, Lone Star and Empire States hardly register, and some surprising underdog states begin to stand out. Maybe Nebraska, the Cornhusker State, should be renamed the Clinical State.
