Comparative Study
Association of back pain frequency with mortality, coronary heart events, mobility, and quality of life in elderly women.
A 5-year observational cohort design using data from a randomized controlled trial of calcium intervention. ⋯ Daily back pain is associated with reduced quality of life, mobility and longevity and increased risk of coronary heart events. The adverse health effects of chronic back pain deserve greater recognition.

Laminoplasty and skip laminectomy for cervical compressive myelopathy: range of motion, postoperative neck pain, and surgical outcomes in a randomized prospective study.
A prospective randomized clinical trial in surgical treatment for cervical compressive myelopathy. ⋯ No significant differences were seen between Lamino and Skip groups, in terms of operative invasiveness, axial neck pain, cervical alignment, and ROM, and clinical results in the patients of CSM without developmental stenosis.

Comparative Study
What is different about workers' compensation patients? Socioeconomic predictors of baseline disability status among patients with lumbar radiculopathy.
Combined analysis of 2 prospective clinical studies. ⋯ Clinical trials involving conditions commonly seen in patients with workers' compensation may need special efforts to ensure adequate representation. Socioeconomic characteristics markedly differed between patients receiving and not receiving workers' compensation. Identifying the independent effects of workers' compensation on outcomes will require controlling for these baseline characteristics and other clinical features associated with disability status.
