Setting proficiency standards for simulation-based mastery learning of short antegrade femoral nail osteosynthesis: a multicenter study.
Article in Acta orthopaedica, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
background and purposeOrthopedic trainees frequently perform short antegrade femoral nail osteosynthesis of trochanteric fractures, but virtual reality simulation-based training (SBT) with haptic feedback has been unavailable. We explored a novel simulator, with the aim of gathering validity evidence for an embedded test and setting a credible pass/fail standard allowing trainees to practice to proficiency. PATIENTS AND
methodsThe research, conducted from May to September 2020 across 3 Danish simulation centers, utilized the Swemac TraumaVision simulator for short antegrade femoral nail osteosynthesis. The validation process adhered to Messick's framework, covering all 5 sources of validity evidence. Participants included novice groups, categorized by training to plateau (n = 14) or to mastery (n = 10), and experts (n = 9), focusing on their performance metrics and training duration.
resultsThe novices in the plateau group and experts had hands-on training for 77 (95% confidence interval [CI] 59-95) and 52 (CI 36-69) minutes while the plateau test score, defined as the average of the last 4 scores, was 75% (CI 65-86) and 96% (CI 94-98) respectively. The pass/fail standard was established at the average expert plateau test score of 96%. All novices in the mastery group could meet this standard and interestingly without increased hands-on training time (65 [CI 46-84] minutes).
conclusionOur study provides supporting validity evidence from all sources of Messick's framework for a simulation-based test in short antegrade nail osteosynthesis of intertrochanteric hip fracture and establishes a defensible pass/fail standard for mastery learning of SBT. Novices who practiced using mastery learning were able to reach the pre-defined pass/fail standard and outperformed novices without a set goal for external motivation.
