Far too few clinical trials are focused on seniors with diabetes, according to an analysis recently published in the journal Diabetologia. Researchers at the Duke University School of Medicine looked at about 2,500 diabetes-related trials that appeared on the ClinicalTrials.gov website between 2007 and 2010. Only 1% of the studies focused specifically on older people, the researchers found. Seniors were “explicitly excluded” from more than 30% of the trials.
