Hi Martin! Sorry to bug you but I have one more question. How do I create the Qdec table without the baseline for that subject? Do I leave the baseline time point out or I still enter it in the table?
For example fsid fsid-base years Study1_Subj1_MRI0. Study1_Subj1. 0 Study1_Subj1_MRI1. Study1_Subj1. 1.25 Study1_Subj1_MRI2. Study1_Subj1. 2.25 OR Study1_Subj1_MRI1. Study1_Subj1. 1.25 Study1_Subj1_MRI2. Study1_Subj1. 2.25 Thanks! Mihaela On Apr 12, 2016 7:13 PM, "Martin Reuter" <mreu...@nmr.mgh.harvard.edu> wrote: > It does not compute this.
