JAMA. 2010;304(15):1673. doi:10.1001/jama.2010.1467

In Reply: Drs Runhaar and van der Wouden raise interesting points about patient population generalizability in our clinical trial. In our view, patients included in our study were representative of patients seen in general clinical practice. Recruitment was 16.4% by general practitioners, 52.0% from chiropractors, 12.0% from physiotherapists, and 19.6% from the newspaper advertisement. In Norway, persons with chronic LBP with or without an acute flare often see different types of health care personnel according to their own preferences.
