Anterior cervical discectomy and fusion beyond radiculopathy: Improvement in vertebral artery flow and dizziness relief.

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
Background: Anterior cervical discectomy and fusion (ACDF) is widely used for cervical disc disease, primarily for neural decompression. However, its potential vascular effects - particularly on vertebral artery hemodynamics and cervicogenic dizziness - remain underexplored. Objective: The objective of this study was to evaluate whether ACDF improves vertebral artery flow and alleviates dizziness symptoms associated with impaired posterior circulation perfusion. Methodology: A prospective case series of 40 patients with cervical radiculopathy or myelopathy underwent ACDF with polyetheretherketone (PEEK) cages. Vertebral artery peak systolic velocity (PSV) was assessed preoperatively and at 1, 3, 6, and 12 months postoperatively using duplex ultrasonography. Functional outcomes were measured with the Visual Analog Scale for neck and arm pain, the Neck Disability Index, and patient-reported dizziness. Radiographic fusion was confirmed at serial follow-up. Results: PSV decreased significantly, indicating improved vertebral artery flow: right side from 48.85 ± 12.71 to 39.0 ± 7.45 and left side from 48.20 ± 12.02 to 41.54 ± 7.56 (both Conclusion: ACDF may alleviate both neural compression and extrinsic vertebral artery compromise, particularly in younger patients. Given the absence of a control group and reliance on surrogate vascular measures, these results should be considered hypothesis-generating rather than definitive.
