title: Comparison of carbamazepine and lithium in the prophylaxis of bipolar disorders. A meta-analysis.
abstract: BACKGROUND
  This meta-analysis assessed the equipotency of carbamazepine and lithium prophylaxis in bipolar disorder.
  
  
  METHODS
  We selected only randomised, double-blind, controlled studies comparing carbamazepine with lithium from a manual and computerised search, and subjected them to a quality inventory. Their statistical results were weighted by their quality score and combined.
  
  
  RESULTS
  Four studies met our criteria, yielding, overall, P = 0.15. This result is not straightforward because the studies showed significant heterogeneity (P < 0.01).
  
  
  CONCLUSIONS
  Differences in statistical power and sensitivity of outcome measure explain this heterogeneity and the conflicting results of the studies. Therefore, the prophylactic efficacy of carbamazepine remains questionable.
