A highly feasible simulation model based on nipple-preserving pork portions for practicing superficial mass resection.
Article in BMC surgery, 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
backgroundSuperficial mass resection is a core surgical skill requiring practical training. Existing simulation models, such as silicone pads or virtual reality, are often costly or inaccessible, creating a need for an affordable and feasible alternative for surgical education.
methodsIn this feasibility study, we developed a low-cost, high-fidelity simulation model using a rind-on pork belly with preserved nipples to practice this procedure and evaluated its efficacy in a skill training study involving 56 surgery residents, whose competency was assessed using a procedure-specific rating scale and the Direct Observation of Procedural Skills (DOPS) tool.
resultsThe pork-based model effectively differentiated competency levels among residents with varying experience. It demonstrated superior fidelity compared to silicone models, without increased operational difficulty, proving particularly suitable for beginners.
conclusionsThis pork-based simulation model is low-cost and easy to prepare, and it represents a high-fidelity training tool, highlighting the possibility of using biological models in hands-on surgical simulation.
