Explanatory Factors for Neck-Related Disability, Headache, and Pain After Cervical Decompression Surgery in Individuals With Cervical Radiculopathy and Neck-Related Headache: A National Registry-Based Study With 2-Year Follow-up.
Article in Neurospine, 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
objectiveTo investigate explanatory factors associated with neck-related disability, headache, and neck and arm pain 2 years after anterior cervical decompression and fusion (ACDF) or posterior cervical foraminotomy (PCF) in individuals with cervical radiculopathy (CR) and neck-related headache.
methodsThis registry-based cohort study used prospectively collected data with a 2-year follow-up from the Swedish Spine Registry. Individuals who underwent ACDF (n=1,866) or PCF (n=357) for CR between January 2016 and March 2021 and reported preoperative neck-related headache were included. Standard analysis of covariance models were used to identify explanatory factors for the absolute values of Neck Disability Index (NDI), NDI-headache, Numerical Rating Scale (NRS) neck pain, and NRS arm pain at the 2-year follow-up after ACDF or PCF.
resultsExplanatory factors explained 33% and 32% of the neck-related disability, 20% and 35% of the headache, 21% and 13% of the neck pain, and 16% and 24% of the arm pain at 2-year follow-up after ACDF and PCF, respectively, in individuals with CR and neck-related headache. The preoperative value of these outcomes had the greatest impact, except for neck and arm pain after PCF, where neck-related disability had a greater impact.
conclusionNeck-related disability, headache, and neck and arm pain after ACDF and PCF in individuals with CR and neck-related headache are associated with preoperative levels of these outcomes, as well as demographic, lifestyle, surgical factors and self-reported health, that should be considered before surgery. The models explained 13%-35% of the variance in the outcomes, indicating that a substantial proportion remains unexplained.
