Hot off the press from our @NIHAging osteoporosis R01: we created a multinational database of older adults in the US and Canada and found extreme shifts in which osteoporosis medications were used over the past decades. Notice anything interesting? tinyurl.com/2762bb6c

Yes. I think it was @mcaronebstat who once wrote that if an assumption is testable, it is unnecessary, except perhaps for computational convenience...
