Dear Editor
We read With great interest the meta-analysis by Chen et al. titled “Meta-Analysis of Treatment for Adjacent Two-Segment Cervical Spondylotic Myelopathy: A Comparison Between Anterior Cervical Corpectomy and Fusion and Anterior Cervical Discectomy and Fusion. 1 ” While the study addresses an important clinical question regarding the treatment of two-level cervical myelopathy, we have concerns regarding the inclusion of the study by Uribe et al. 2 Upon careful review, we found that Uribe et al.’s study does not meet the inclusion criteria for this meta-analysis. Specifically, it involves pathology affecting multiple levels (more than two), and the results are not specific to two-level cervical myelopathy. We suggest that the Uribe et al. 2 study be excluded from the analysis to ensure more accurate results. Furthermore, given the significant heterogeneity in operating time and blood loss observed in the original analysis, it would be valuable to reassess the data after excluding the Uribe et al. 2 study to determine whether the overall conclusions of the meta-analysis are affected.
