However, a meta-analysis of observational trials cannot correct for biases, errors, and problems, and, in fact, it magnifies them," Dr Speroff asserted.
Although results from observational trials seem promising, controlled trials have produced equivocal results.
The methodology will then be tested in 3 paediatric observational trials (risperidone in conduct disorder; fluoxetine in depression, and montelukast in bronchial asthma) and standardized, which can be used pharmacovigilance and in epidemiological, observational, and registration trials.
