a At all participating sites across training rounds showing that the score is greater for sub-compartments with larger volumes. b For a site with problematic annotations (Site 48). The instability in these curves could be caused by errors in annotation for the local validation data (similar to errors that were observed for a small shared sample of data from this site). c Provides an example of a case with erroneous annotations in the data used by Site 48. Equivalent plots for Jaccard similarity coefficient (JSC) can be observed in supplementary figures.
