A growing minority of models report external validation and geographic transfer
Most claims rest on internal cross-validation or single-institution splits; systematic reviews of medical-imaging AI (e.g. head-CT CNN meta-review) find external validation rare, reporting-standard adherence poor, and glioma-specific systematic external-validation evidence even sparser
Governs whether any of this reaches deployment; core reproducibility problem
