Risk of Traumatic Injury 76% Lower Visiting a Chiropractor than a Primary Care Physician- by The Evidence Based Chiropractor

Just today SPINE released an epub ahead of print which found, "Among Medicare beneficiaries aged 66-99 with an office visit risk for a neuromusculoskeletal problem, risk of injury to the head, neck or trunk within 7 days was 76% lower among subjects with a chiropractic office visit as compared to those who saw a primary care physician."

That is a startling difference in risk. While, in my opinion, the safety and efficacy of chiropractic care is well documented, it took me by surprise to see the dramatic results of this study. 

Below I have included a direct link to the Pubmed page. What are your thoughts on this new research?
