Cervical Disc Replacement Does Not Increase Revision or Reoperation Risk Compared With Fusion in Osteoporotic Women: A Retrospective Matched Cohort Study.
Article in Global spine journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Study DesignRetrospective Cohort Study.ObjectivesCervical disc arthroplasty (CDA) and anterior cervical discectomy and fusion (ACDF) are both safe and effective surgical options for cervical spine pathologies such as myelopathy and radiculopathy. Comparative outcomes data for CDA versus ACDF in osteoporotic female patients remain limited despite this population's increased vulnerability to postoperative complications. This study compares postoperative outcomes and healthcare utilization between single-level ACDF and CDA in this patient group.MethodsAdult female patients aged ≥55 years with osteoporosis who underwent single-level CDA or ACDF between 2010 and 2022 were identified using the PearlDiver national database. A one-year washout period for prior cervical surgeries was applied, and patients receiving both procedures simultaneously were excluded. Eligible patients were matched three-to-one on age, Elixhauser Comorbidity Index (ECI), and smoking history. Outcomes included 90-day medical and surgical complications and 30-day, 90-day, and 2-year healthcare utilization metrics. Welch's t-tests and Pearson χ2 tests were used for all comparisons. Statistical significance was set at
