title: Relationship between antidepressant partial and nonresponse and subsequent response to antidepressant augmentation.
abstract: OBJECTIVE
  To evaluate the relationship between the degree of antidepressant nonresponse and subsequent response to lithium and triiodothyronine (T3) augmentation.
  
  
  METHODS
  This is a retrospective analysis of data combined from two previous controlled studies of lithium and triiodothyronine augmentation of tricyclic antidepressants.
  
  
  RESULTS
  There was no difference in the rate of augmentation response between partial and nonresponders to tricyclic antidepressant treatment.
  
  
  CONCLUSIONS
  Augmentation response does not appear to be related to the degree of nonresponse to the preceding antidepressant trial.
