Abstract
The main goal in this paper is to describe how articles on clinical trials on atypical
antipsychotic drugs in bipolar disorder reported their design. 25 controlled clinical
trials were identified. Data were extracted on the general characteristics of the
studies, including sources of funding, study design, and ethical issues. Most trials
adequately report design issues such as patient selection, randomization, and flow
of patients. However, only 8 of 25 studies reported pre-estimation of sample size;
22 articles claimed a double-blind design, but only 3 reported details on how blinding
was performed; 17 trials failed to explicitly adhere to the Declaration of Helsinki.
