Study Design: Randomized trial with concurrent observational cohort. A total of 1171 patients were divided into subgroups by educational attainment: high school or less, some college, and college degree or above.
Objective: To assess the influence of education level on outcomes for treatment of lumbar disc herniation.
Study Design: As-treated analysis of the Spine Patient Outcomes Research Trial.
Objective: To compare baseline characteristics and surgical and nonoperative outcomes in degenerative spondylolisthesis (DS) and spinal stenosis (SpS) patients stratified by predominant pain location (i.e.
Study Design: Subgroup analyses according to treatment received.
Objective: To evaluate whether baseline radiographic findings predicted outcomes in patients with degenerative spondylolisthesis.
Summary Of Background Data: The spine patient outcomes research trial combined randomized and observational DS cohorts.

Background: The Spine Patient Outcomes Research Trial showed an overall advantage for operative compared with nonoperative treatment of lumbar disc herniations. Because a recent randomized trial showed no benefit for operative treatment of a disc at the lumbosacral junction (L5-S1), we reviewed subgroups within the Spine Patient Outcomes Research Trial to assess the effect of herniation level on outcomes of operative and nonoperative care.
Methods: The combined randomized and observation cohorts of the Spine Patient Outcomes Research Trial were analyzed by actual treatment received stratified by level of disc herniation.
