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

Introduction: This study aimed to evaluate fresh-frozen cadavers (FFC) as a novel model for percutaneous nephrolithotomy (PCNL) training, focusing on ultrasound-guided supine PCNL. Methods: Sixteen urologists participated in a 2-day course at a tertiary center to assess the utility of an FFC model for ultrasound-guided supine PCNL. After the procedure, the participants completed a 24-question evaluation of the FFC model using a 5-point Likert scale. The questionnaire assessed tissue quality, US imaging, procedural steps, overall experience compared to live patient procedures, and suitability of the model for both basic and advanced supine PCNL training. Results: The tactile sensation, skin stiffness, and distensibility of the calyces resembled real-life scenarios as the cadavers thawed. Similarly, US quality was worse in frozen cadavers and improved after irrigation with the collection system. Valdivia-Galdakao positioning is considered more difficult than in real life, because of rigor mortis. Conclusion: FFC demonstrated robust content validity as a training model for PCNL. The model provides a realistic and effective training experience, offering a promising tool for developing critical surgical skills, while minimizing radiation exposure and procedural risks.
