====== Mild Degenerative Cervical Myelopathy ======

Khosravi et al. included studies with Mild [[degenerative Cervical Myelopathy]] which was defined as a [[modified Japanese Orthopaedic Association scale]] [[score]] of 15 to 17 or a [[Japanese Orthopaedic Association scale]] score of 13 to 16. Independent [[reviewer]]s screened all the [[record]]s, and discrepancies between the reviewers were solved in a session with the [[senior]] author. For risk of bias assessment, [[RoB 2]] tool was used for [[randomized clinical trial]]s and ROBINS-I for non-randomized studies.

After screening 6 087 [[manuscript]]s, only 8 studies met the [[inclusion criteria]]. Lower pre-operative [[mJOA]] scores and quality-of-life measurement scores were reported by multiple studies to predict better surgical outcomes compared to other groups. Pre-operative [[Increased signal intensity magnetic resonance imaging on T2 weighted image of the cervical spinal cord]] was also reported to predict poor outcomes. [[Neck pain]] before [[intervention]] resulted in improved patient-reported outcomes. Two studies also reported motor symptoms prior to surgery as outcome predictors.

Lower [[quality of life]] before surgery, [[neck pain]], lower pre-operative mJOA scores, motor symptoms before surgery, [[female]] gender, gastrointestinal comorbidities, surgical procedure and surgeon's experience with specific techniques, and high signal intensity of cord in [[T2]] MRI were the surgical outcome predictors reported in the literature. Lower Quality of Life (QoL) score and neck prior to surgery were reported as predictors of the more improved outcome, but [[increased signal intensity magnetic resonance imaging on T2 weighted image of the cervical spinal cord]] was reported as an unfavorable outcome predictor
