Correction

In the February review article “Long-Term Lithium Therapy for Bipolar Disorder: Systematic Review and Meta-Analysis of Randomized Controlled Trials” by Geddes et al. (Am J Psychiatry 2004; 161:217–222), there was an error in Table 1: the previous lithium use in the Kane et al. 1982 study should have been listed as “Unclear.” Also, in Figure 3, the rate of depressive relapse with placebo in the Bowden et al. 2003 study should have been 30% (N=21 of 70). The pooled depressive relapse rate with placebo was therefore 30% (N=89 of 297) rather than 32%. The pooled fixed effect relative risk (reported on p. 219) was 0.83 (95% CI=0.63–1.08), and the random effects relative risk was 0.85 (95% CI=0.66–1.11). These changes do not materially change the conclusions of the article.
