NPVs based on % improvement at Week 2, corresponding with completion of 10 TMS sessions. All NPVs reported in %. For all parameters tested, NPVs were lower when overall outcome was determined using final scores vs. those collected at week 4 (treatment 20). T₂₀ = Treatment session #20; T_F = Final treatment session;
