Total subjects (n) are listed for each study, then Dice score and volume correlation with 95% confidence interval (95% CI). RMSE is the root mean squared error in ml. Abs. Vol. Diff. is the absolute volume difference in ml by median and interquartile range.. %< 5ml is the percentage of predictions that were within 5ml.
