  Evidencepartial

  In this work, we developed a three-step protocol for evaluating robustness to H&E staining variation in CPath models. Step 1: Select reference staining conditions, Step 2: Characterize test set staining properties, Step 3: Apply CPath model(s) under simulated reference staining conditions.

  Implicationpartial

  The abstract explicitly states the development of this protocol and outlines its three steps.
