Including mixed-effects models for statistical analysis is especially solid because they’re built to handle variability in performance between individual radiologists, which is common in medical imaging studies, and they’re already widely used in neuroimaging and other clinical research for this exact reason. This approach should help you draw stronger, more generalizable conclusions by accounting for the natural differences in reader skill and experience, so your results will be less skewed by outlier performances or differing baselines. If you want to push things further, you might consider expanding your mixed-effects approach to model hierarchical data structures (e.g., cases within radiologists, radiologists within centers) or integrating deep learning mixed-effects layers if Grok-4 produces multi-dimensional imaging features, as has been done in some recent imaging AI studies.
