Which of the drugs (if either) was more successful in preventing the recurrence of depression relative to the placebo?
Alex17521 [72]

The results also question the effectiveness of Lithium in general since the percentage of patients who had a recurrence of depression in the Placebo group (67.65%) is only slightly higher than that of the Lithium group (62.16%).
