Standalone laminectomy for degenerative cervical myelopathy in elderly patients: Predictive value of T1 slope minus cervical lordosis for clinical outcomes at 2 years

This dataset supports a retrospective cohort study investigating the predictive role of preoperative T1 slope minus cervical lordosis (T1S–CL) in predicting clinical outcomes (including achievement of minimal clinically important difference [MCID]) at 2 years after standalone laminectomy in elderly patients with degenerative cervical myelopathy (DCM).
