| Measure | Time frame |
|---|---|
| Response or non-response. In accordance with the CAN-BIND study7, response is defined as a greater than 50% reduction in MADRS score8 at week 8 when compared to baseline. Success of the DEPREDICT algorithm to predict treatment response will be judged based on the calculated sensitivity/specificity of the algorithm (which is based on both baseline-, and/or the 2 week MRI scan, as well as clinical variables and information on sleep and activity) to predict clinical outcome (MADRS-non-response). | — |
