Robotic-Assisted Computed Tomography-Guided Percutaneous Bone Procedures: A Prospective Multicenter Pilot Study.
Trial report in Cardiovascular and interventional radiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06376682 (Evaluation of the EPIONE Robotic System for Image-guided Percutaneous Bone Procedures A Prospective Study on Feasibility, Safety and Accuracy), which is not on this map.

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.

Abstract
purposeTo prospectively evaluate the feasibility, safety, and targeting accuracy of robotic-assisted CT-guided percutaneous bone procedures. MATERIALS AND
methodsThis prospective multicenter pilot study included adult patients undergoing CT-guided percutaneous bone consolidation or tumor ablation between September 2024 and January 2025 at three academic institutions. All procedures were planned and performed using the Epione® robotic platform. Targets included the thoracic and lumbar spine and the pelvis. The primary endpoint was feasibility of robotic-assisted needle insertion, defined as successful needle placement without conversion to manual technique. Secondary endpoints included safety, targeting accuracy, procedural time, and radiation dose. Targeting accuracy was measured as lateral tip deviation and angular deviation between planned and final needle positions.
resultsThirty-four patients underwent 90 needle insertions, including 66 in the spine (73.3%) and 24 in the pelvis (26.7%). Indications were bone consolidation in 87/90 insertions (97%) and tumor ablation in 3/90 (3%). Robotic insertion was feasible in 89/90 insertions (98.9%). Seven adverse events occurred in 6 patients (17.6%), including four serious events, none related to the device or procedure. Mean lateral tip deviation was 2.0 ± 1.4 mm, and mean angular deviation was 3.1° ± 2.7°. Mean dose-length product was 3224 ± 2215 mGy.cm. Mean total procedure time was 03 h 09 min ± 50 min.
conclusionsRobotic-assisted CT-guided bone procedures showed high feasibility and satisfactory targeting accuracy, with no device- or procedure-related adverse events. These findings support further evaluation in larger comparative studies. CLINICAL
