Association between reduced cervical extensor muscle mass and postoperative outcomes after single-door laminoplasty in elderly patients with cervical spondylotic myelopathy: a retrospective study.
Article in Annals of medicine, 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
backgroundTo investigate the association between preoperative cervical extensor muscle fatty infiltration and postoperative clinical and radiographic outcomes after posterior open-door laminoplasty in elderly patients with cervical spondylotic myelopathy (CSM).
methodsElderly patients (>60 years) who underwent first-time posterior single-door laminoplasty for multilevel CSM between January 2015 and December 2020 were retrospectively reviewed. All patients had a minimum follow-up of 12 months. Fatty infiltration of cervical extensor muscles was assessed on preoperative MRI using the Goutallier grading system and classified as mild, moderate, or severe. Clinical outcomes (Japanese Orthopaedic Association [JOA] score, Neck Disability Index [NDI], Visual Analog Scale [VAS]), minimal clinically important difference (MCID), perioperative parameters, and cervical sagittal alignment were evaluated.
resultsA total of 101 patients were included (mild:
conclusionSevere fatty infiltration of cervical extensor muscles is associated with poorer neurological recovery, prolonged hospitalization, and sagittal imbalance after laminoplasty in elderly CSM patients. Preoperative MRI-based muscle quality assessment may improve risk stratification and guide surgical planning and postoperative rehabilitation.
