Task 2 and 3 output: PFS # of days accepted or not?

Responding for the sake of future reference in case it helps other participants. I submitted the predictions in days multiplied by -1 and this seems to have worked.

Best,

Task 2 and 3 output: PFS # of days accepted or not?

Hello,

We have calculated our prediction output for Task 2 and 3 to be measured in the number of PFS days. Previously, instructions for Task 2 and 3 indicated that the output could be concordant with the PFS in days (e.g predicted PFS days). This is also mentioned in the discussion post here: Task 2 & 3 output. However, on the submission page, it explicitly states: “Reminder: For tasks 2 and 3, the scores should be anti-concordant with the PFS time (e.g. hazard score).”. Moreover, on the Overview page (Results submission format section), it states: “If you have a concordant output (e.g predicted PFS days), you can simply submit your_estimate times -1.”. Does this imply we can submit the number of days if we multiply -1 with the answer?

This is all a bit confusing. Can we submit our predictions as the number of days or not? Any insight or advice would be appreciated.

Thank you for your time.

Kareem
