Limitations and Caveats
Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
Free participation and the focus on glucosamine may attract a certain type of patients with specific personality traits. Adjunctive management was permitted, which may influence outcome. Compliance was assessed by capsule counts.
