Patients are divided into two groups. One group receives stem cells and the other a placebo injection. Both groups start with a mean amplitude of glycemic excursions of 18030mg per deciliter at baseline before intervention. After 4 weeks the placebo group has an unchanged profile of excursions, but the experimental group has a reduction in excursions to 10050mg per deciliter. How many patients would be needed to find a p 0.05 between the groups?
