Very different magnitude of values for AUC Values

Looking the AUC values of Drug Sensitivity AUC (PRISM Repurposing Secondary) v/s Drug Sensitivity AUC (CTD^2), the magnitudes of the values are extremely different. Drug Sensitivity AUC (PRISM Repurposing Secondary) values are much similar to datasets like GDSC2

Why is that?

Could be that the values from Drug Sensitivity AUC (CTD^2) are computed without a fitted logistic regression?


Hi mavergara,

Yes, CTD2 AUC values are the ones originally published in the associated paper and they are not normalized to the covered dose ranges, while for GDSC and PRISM we refit the curves by normalizing the computed AUC’s to the measured dose range (i.e. AUC values are typically between 0 and 1).

You can normalize them by dividing them to their maximum value (16 for most compounds).
