Clinical Outcomes Following Three- and Four-Level Anterior Cervical Discectomy and Fusion: A Systematic Review and Meta-Analysis.
Review in Global spine journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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 Design/SettingSystematic review and meta-analysis.ObjectivesAnterior cervical discectomy and fusion (ACDF) is a well-established treatment for degenerative cervical pathology. Although outcomes following 1- and 2-level ACDF are favorable, increasing construct length has been associated with worse outcomes. Despite this, 3- and 4-level ACDF are often grouped as "multilevel" constructs, though emerging evidence suggests 4-level ACDF may carry greater risk. This study systematically reviewed the literature and performed a meta-analysis comparing outcomes between 3- and 4-level ACDF.MethodsA systematic search of MEDLINE, Embase, and Cochrane databases was performed per PRISMA guidelines. Studies reporting outcomes following three- or four-level ACDF were included.
