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

objectiveThe aim of this study was to report the early clinical experience with stereotactic biopsy using the Medtronic Stealth Autoguide Cranial Robotic Guidance Platform, representing the first relevant clinical study in the Republic of Korea (ROK). We evaluated potential advantages and limitations related to workflow integration, instrument setup, procedural efficiency, accuracy, and safety.

methodsA retrospective case series was conducted across three centers in the ROK. From April to July 2025, 17 consecutive patients underwent frameless stereotactic biopsy using the Stealth Autoguide system. Data on demographics, operative time, and complications were collected, and descriptive analyses were performed.

resultsBiopsy using the Stealth Autoguide System was successfully completed in 16 of 17 patients. The median operative time was 48 minutes (interquartile range, 33-64), and the median target alignment error was 0.4 mm (interquartile range, 0.3-0.6). One case required conversion to the conventional manual method due to targeting inaccuracy. Three cases of asymptomatic intracerebral hemorrhage occurred, including one at the tissue-harvest site and two with cortical hemorrhage, all of which were managed conservatively.

conclusionThe Stealth Autoguide system facilitates a more efficient frameless stereotactic biopsy than conventional methods by reducing operative time, enhancing accuracy, and allowing for a smaller, muscle-sparing incision. However, some concerns remain, and further clinical validation is needed to define its optimal indications and safety profile.
