AUTHORS ' CONCLUSIONS There was adequate efficacy evidence for lithium or antidepressants preventing relapse in unipolar affective disorder , however their relative efficacy was unknown .
BACKGROUND The main rationale for the use of lithium in the long-term treatment of unipolar affective disorder is its efficacy in treating bipolar affective disorder and resistant depression .
However , there is considerable uncertainty about which pharmacological intervention is most effective in the long-term treatment of recurrent unipolar affective disorder .

The recruitment process for a multicenter study on the long-term prophylactic treatment of affective disorders.
The paper reports on the process of patient recruitment for a controlled clinical multicenter study on the treatment of affective disorders . Two thirds of the patients screened did not participate because prophylactic treatment was either unnecessary or not justified for medical reasons . Further , a number of patients equal to that eventually allocated to the trial refused to participate for personal , idiosyncratic reasons . In spite of this , the patients in the trial were very similar to those not participating with respect to relevant variables such as age , sex , number of and intervals between previous episodes or severity of the present episode
