Evaluating Cadaveric Simulation Versus Traditional Instruction for Teaching Ultrasound-Guided Serratus Anterior Plane Blocks: Effects on Procedural Competency.
Article in Cureus, 2025. 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
backgroundMedical education often relies on lecture-based instruction and videos to teach procedural skills. However, cadaveric-based training offers a more hands-on approach that may enhance procedural competency. This study evaluates the efficacy of cadaveric model training in teaching medical students the serratus anterior plane block (SAPB) compared with traditional lecture- and video-based instruction.
objectiveThe objective of this study is to compare the procedural competency of medical students trained using a traditional method (lecture + video) versus those receiving additional cadaveric model practice. We hypothesized that cadaveric training would lead to greater proficiency in performing the SAPB.
methodsA randomized comparative study was conducted with 26 medical students assigned by computer-generated allocation to either a traditional instruction group (lecture + video; n = 13) or an intervention group (lecture + video + cadaveric training; n = 13). All participants completed a pre-study knowledge survey followed by standardized instruction. The intervention group additionally received hands-on cadaveric practice. Within one week, all students completed a 32-point procedural competency assessment and a post-study knowledge survey. Knowledge scores and procedural performance were compared between groups using independent samples t-tests.
resultsThe intervention group demonstrated significantly higher procedural competency scores than the traditional instruction group, particularly in key steps such as transducer positioning, needle insertion, and injection site preparation. Both groups showed similar improvements in written knowledge (pre- vs. post-test), with no significant difference between groups (p > 0.05). In contrast, procedural performance scores were significantly higher in the cadaveric training group (p < 0.05).
conclusionCadaveric model training significantly enhances procedural competency in medical students learning the SAPB compared with traditional lecture- and video-based instruction. While written knowledge gains were comparable, hands-on cadaveric experience provided a key advantage in developing clinical procedural skills. These findings support incorporating cadaveric-based instruction into procedural skill curricula for improved bedside preparedness.
