Incorporating a dynamic extraocular muscle simulation model into the undergraduate ophthalmic curriculum.
Article in BMC medical education, 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
backgroundLearning the anatomy of extraocular muscles and their coordination in eye movements is challenging for undergraduate medical students. We developed a dynamic extraocular muscle simulation model and integrated it into the undergraduate ophthalmic curriculum to evaluate its educational impact.
methodsA custom simulation model of binocular muscles was developed and assessed for educational effectiveness in undergraduate education. In a comparative study, 84 students from Peking Union Medical College were assigned to either the simulation group (one-hour didactic lecture followed by a half-hour simulator practice) or the traditional teaching group (one-hour didactic teaching followed by a half-hour video review). All students were given 5-point quizzes on the anatomical and functional basics of extraocular muscles before the lecture(Q1), after the lecture(Q2), and after simulator practice/video-review(Q3). Within each group, the scores of Q2 were compared with Q1, and the scores of Q3 were compared with Q2. The effectiveness of the simulation model was evaluated by comparing the improvements in scores from Q2 to Q3 between the two groups. Nonparametric tests were used for statistical analysis.
resultsThe simulation and traditional teaching groups were well-matched in terms of age, gender, Grade Point Average (GPA), and average Q1 and Q2 scores. The simulation group demonstrated significant improvements after both the didactic lecture and simulator practice. In contrast, the traditional teaching group showed significant improvement only after the lecture, not after the video review. The simulation model led to greater learning improvements compared to video review (mean(standard deviation)): 0.64(1.23) vs 0.05(0.79), P = 0.006.
conclusionsThe extraocular muscle simulation model is a valuable adjunct to traditional teaching methods in undergraduate medical education. Simulation-based education should be encouraged for teaching complex anatomical topics.
