Comparison of Titanium and Carbon Fiber-Reinforced Polyetheretherketone Spinal Implants in Postoperative Spine Stereotactic Body Radiation Therapy: A Comprehensive Review of Current Evidence and Future Perspectives.
Review in Advances in radiation oncology, 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
Postoperative stereotactic body radiation therapy (SBRT) for spinal metastases presents technical challenges, particularly in the presence of internal fixation devices. Titanium implants-the standard implant material-cause substantial imaging artifacts in computed tomography (CT) and magnetic resonance (MR) scans, which can lead to target and organ-at-risk contouring problems and compromise the accuracy of dose calculations. Meanwhile, carbon fiber-reinforced polyetheretherketone (Carbon/PEEK) implants have emerged as radiolucent alternatives with favorable imaging properties. This review summarizes the current evidence comparing titanium and Carbon/PEEK implants in the context of postoperative spine SBRT, focusing on differences in artifact size in CT and MR imaging, contouring accuracy, dose perturbation, dose calculation accuracy, image guided radiation therapy, radiation therapy robustness to setup error, and clinical outcomes in photon and proton therapies.
