Initial Outcomes of Zap-X Stereotactic Radiosurgery for the Treatment of Spinal Tumors: A Case Series.
Article in Cureus, 2025. 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
Stereotactic radiosurgery (SRS) is an established modality for managing spinal tumors, offering targeted radiation while preserving adjacent critical structures. The ZAP-X gyroscopic SRS system (ZAP Surgical Systems, Inc., San Carlos, CA) introduces a novel, self-shielded, non-isocentric platform that may expand access to SRS and streamline treatment delivery. This study presents initial clinical outcomes and technical feasibility of ZAP-X in treating spinal tumors. Three patients with spinal tumors, including schwannoma, meningioma, and spinal metastasis, were treated using ZAP-X SRS between February and June 2024. All patients underwent single-session treatment with no acute complications or radiation-related side effects. One patient with spinal metastasis and advanced comorbidities experienced significant pain relief, and another demonstrated a complete resolution of neurological symptoms with no radiographic tumor progression at three- and five-month follow-up. The third patient expired due to unrelated causes, but tolerated treatment without complications. Early experience suggests that ZAP-X SRS is a safe, accurate, and effective option for treating spinal tumors. Its compact design and streamlined workflow offer potential advantages in both definitive and palliative care settings. Further investigation in larger cohorts with extended follow-up is warranted to validate long-term efficacy and broader clinical utility.
