Bow hunter's syndrome secondary to lateral and posterior spondylosis: illustrative case.
Article in Journal of neurosurgery. Case lessons, 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
backgroundBow hunter's syndrome (BHS) is a rare form of rotational vertebral artery (VA) insufficiency, most commonly attributed to osteophytic compression at the subaxial cervical spine. While single-segment compression is frequently reported, dual-segment involvement remains exceedingly rare. OBSERVATIONS: The authors report the case of an 82-year-old male who presented with recurrent vertigo triggered by head rotation. Dynamic imaging revealed rotational occlusion of the left VA secondary to simultaneous lateral and posterior compression at both C4-5 and C5-6 levels, caused by osteophytes of the uncovertebral and facet joints. The patient underwent successful anterior cervical discectomy and fusion from C4 to C6, along with targeted resection of the osteophytes. Postoperatively, rotational symptoms resolved completely, and follow-up imaging confirmed restoration of VA patency. LESSONS: This case highlights the importance of considering multilevel, multidirectional osteophytic compression in the evaluation of BHS. To the authors' knowledge, this represents the first documented instance of BHS resulting from concurrent lateral and posterior compression at two adjacent cervical levels, emphasizing the need for comprehensive vascular and bony assessment in atypical presentations. https://thejns.org/doi/10.3171/CASE25718.
