TY - JOUR T1 - EFfect of oral glucosamine on pain-related disability in patients with chronic low back pain AU - Runhaar J, van der Wouden JC Y1 - 2010/10/20 N1 - 10.1001/jama.2010.1466 JO - JAMA SP - 1673 EP - 1673 VL - 304 IS - 15 N2 - However, based on the information given in the article, we find it hard to assess the generalizability of the study findings. The authors described that recruitment occurred via general practitioners, physiotherapists, chiropractors, and self-referrals through a newspaper advertisement. It would be helpful to know the distribution of included participants among these 4 methods of recruitment. Self-referred participants had to meet the additional requirement of a recent magnetic resonance imaging (MRI) scan, but it would be helpful to have more information about the Norwegian health care system to understand the implications of this route. A more precise description of the way the investigators recruited the participants would also result in a clearer description of the study population.
