Spinal cord MRI signal changes at one year after cervical decompression surgery is useful for predicting mid-term clinical outcome: an observational study using propensity scores

There is little information on the relationship between magnetic resonance imaging (MRI) T2-weighted high signal change (T2HSC) in the spinal cord and surgical outcome for cervical myelopathy. We therefore examined whether T2HSC regression at one year postoperatively reflected 5-year prognosis after adjustment using propensity scores for potential confounding variables, which have been a disadvantage of earlier observational studies.
