Carbamazepine for schizophrenia and schizoaffective psychoses.
Synthesis in The Cochrane database of systematic reviews, 2000. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundA sizeable minority of people with schizophrenia do not have complete remission of symptoms. A variety of adjunctive treatments have been used to treat schizophrenia, carbamazepine being one.
objectivesTo review the effects of carbamazepine and its derivatives for the treatment of schizophrenia and schizoaffective psychoses. SEARCH STRATEGY: Biological Abstracts (1980-1998), The Cochrane Library (Issue 3, 1998), The Cochrane Schizophrenia Group's Register of Trials (August 1998), EMBASE (1980-1998), MEDLINE (1966-1998), PsycLIT (1886-1998) and PSYNDEX (1974-1998) were searched. Citations from included trials were also inspected and relevant companies and authors contacted for additional data. SELECTION CRITERIA: All randomised controlled trials comparing carbamazepine, or compounds of the carbamazepine family, to placebo or no intervention, whether as sole treatment or as an adjunct to antipsychotic medication for the treatment of schizophrenia and/or schizoaffective psychoses. DATA COLLECTION AND ANALYSIS: Citations and, where possible, abstracts were independently inspected by reviewers, papers ordered, re-inspected and quality assessed. Data were extracted independently by at least two reviewers. Dichotomous data were analysed using Peto odds ratio (OR) and the 95% confidence interval (CI) estimated. Where possible the number needed to treat (NNT) or number needed to harm statistics were calculated. MAIN
resultsThere is no clear effect of carbamazepine as the sole maintenance treatment for those with schizophrenia. Eight trials provided very limited data on the value of carbamazepine as an adjunct to antipsychotics. Studies were small and poorly reported. Currently no published data provides convincing evidence that adjunctive carbamazepine has an effect on global functioning, mental state, side effects or acceptability of treatment. REVIEWER'S
conclusionsBased on currently available randomised trial-derived evidence, carbamazepine cannot be recommend for routine clinical use for treatment or augmentation of antipsychotic treatment of schizophrenia. However, for those with a past history of being responsive to carbamazepine, or for those with associated EEG abnormalities, a trial of the drug may be warranted. More data is expected from trialists and the results of this review may be changed by their inclusion. At present large, simple well designed and reported trials are justified especially if focusing on those with both schizophrenia and EEG abnormalities or violent episodes and people with schizoaffective disorders.
