So we've got a couple of small pilot clinical trials. The best one was a randomized controlled trial. I think it only included 26 subjects, something like that, randomized to 12 weeks of a low fat diet, 10-week washout, 12 weeks of ketogenic diet. Some of the participants got keto first and then low fat. Other participants got low fat then keto. And that trial actually found that when patients were in ketosis, they had statistically significant improvement in activities of daily living and quality of life. And they did have improvement in cognitive function. But it didn't reach statistical significance, that improvement did not.
