Log odds ratio for the associations between likelihood of response to bupropion and sertraline with (a) probabilistic reward task, (b) verbal fluency task, and (c) Eriksen flanker task. Better response bias, greater verbal fluency, and higher response interference were specifically associated with greater likelihood of response to bupropion in patients who previously failed to respond to sertraline. ⍿p < 0.10, *p < 0.05, **p < 0.01, ***p < 0.001.
