    AI performance in pediatric wrist fracture detection is significantly influenced by the composition of test sets used in evaluations.

  • 2

    A balanced test set, featuring a mix of easy and difficult cases, yields different performance metrics compared to a randomly selected test set.

  • 3

    The study utilized the GRAZPEDWRI-DX dataset, categorizing X-ray images based on fracture visibility to assess AI model performance.

  • 4

    Different sampling strategies impact the predictive performance of deep-learning models, highlighting the importance of case complexity.

  • 5

    The lack of a standardized reference test set hinders objective performance comparisons among various AI solutions in clinical practice.
