Abbreviations: ACDF, anterior cervical discectomy and fusion; aOR, adjusted OR; MLCF, middle-to-lower cervical fusion; NS, neurological symptoms; UCF, upper cervical fusion.
Note: Estimates that are bolded are significantly different from 1 (P < 0.05).
↵a The current analysis included only African American/Black and Caucasian/White patients. The models failed to converge when including other race categories due to small cell counts.
↵b Patients were classified as UCF or MLCF based on the inclusion of C3 to C4 level in the ACDF construct.
↵c aOR was calculated including age, sex, race, insurance type, number of levels fused, spinal cord signal change, and diagnosis as covariates.
