No distinction is made between raw and normalized pseudovalues since the trapezoid estimate is the same for either type of pseudovalues. Original: original DBM; new: new model simplification; new plus ddfH: new model simplification plus ddfH; min: minimum; max: maximum; SD: standard deviation; CI width: width of a 95% confidence interval for the difference of the AUC estimates.
