Patient Characteristics

Responders and non-responders are similar with respect to other mental problems so diagnosis may not help predict patient outcome.

Baseline SPECT Boxplots

There do not appear to be obvious differences in SPECT scores between responders and non-responders across brain regions. A linear model with only brain region scores will not distinguish the patients. However, among patients with certain diagnosis, there are some differences in several brain regions, which suggest effect modification.
