1 · What the graph read from it

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.

2 · The registry

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

backgroundTo evaluate the feasibility, safety, and workflow integration of augmented reality (AR)-assisted visualization using the Apple Vision Pro headset during live biliary interventions incorporating cholangioscopy. MATERIALS AND

methodsIn this single-center, IRB-approved pilot study, four biliary interventions were performed by a single attending interventional radiologist wearing an AR headset. Cholangioscopic video output from the SpyGlass™ DS system was transmitted via HDMI/SDI encoders over a local area network and rendered as virtual displays within the headset. The AR interface functioned as the primary visualization modality for guidance during each procedure.

resultsFour complex biliary cases were performed-all procedures were technically successful (100%) without complications (0%). AR-assisted visualization enabled continuous intraprocedural integration of cholangioscopy without technical failure, latency-related interruption, or breach of sterility. Qualitative operator feedback suggested improved procedural continuity, enhanced visualization during balloon dilation and stent deployment, and reduced need for repetitive head movement between monitors. The system was successfully incorporated into the standard sterile procedural workflows.

conclusionAR-assisted cholangioscopy during live biliary interventions is technically feasible and safe in this initial clinical experience. Spatial computing platforms may provide workflow consolidation and ergonomic advantages during complex procedures.
