Simulation-based mastery learning for nasolacrimal duct probing in ophthalmology residency: a prospective pre-post educational study.
Article in BMC medical education, 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
backgroundNasolacrimal duct probing is traditionally taught through supervised practice on pediatric patients; however, limited case availability and ethical concerns restrict training opportunities. Simulation-based mastery learning (SBML) offers a structured alternative. We developed a multifaceted probing simulation (MPS) incorporating SBML principles for ophthalmology resident training.
methodsThis prospective pre–post interventional study evaluated feasibility (process outcomes) and preliminary educational outcomes of the MPS program. Twenty ophthalmology residents at a university in Thailand participated. Training included a video tutorial, MCQ assessment with feedback, and supervised simulation-based practice. Feasibility outcomes included implementation, completion rate, and usability (User Experience Questionnaire; UEQ). Educational outcomes included changes in procedural performance (rubric scores), procedure time, and self-reported confidence.
resultsAll participants completed the training program, supporting feasibility of implementation. The simulation demonstrated high usability across all UEQ domains, with attractiveness rated highest, and excellent internal consistency (Cronbach’s alpha = 0.91). Median procedural performance scores improved from 16 (IQR 13.5–19) to 26.5 (IQR 24–29.5), while mean procedure time decreased from 3.45 ± 1.32 to 1.53 ± 0.42 min (p < 0.001). Confidence levels increased progressively throughout training.
conclusionsThe MPS program appears feasible and acceptable for integration into ophthalmology residency training. Improvements in procedural performance, efficiency, and confidence were observed immediately after training, indicating short-term benefits; however, these findings are preliminary. Long-term retention and transfer to clinical practice were not assessed. Further controlled studies are required to determine effectiveness and clinical impact.
