2008 BMD: -2.8, -2.5, -2.1 Healthy 80 year old retired female pharmacist. Very active (excellent walker). Completed 5 years of Didrocal in 2009. She's not keen on medications (ie. another bisphosphonate). I wonder if it is time to look into improving her BMD. But I think it's a stretch to say there has been a significant decrease. What is the 95% confidence interval on BMD measurements anyway ? Probably more than 0.022
