Meta Analysis
Tobacco control policies and perinatal and child health: a systematic review and meta-analysis protocol.
Children experience considerable morbidity and mortality due to tobacco smoke exposure. Tobacco control policies may benefit child health by reducing this exposure. We aim to comprehensively assess the effects of the range of tobacco control policies advocated by the WHO on perinatal and child health. ⋯ No ethical assessment is necessary as we will summarise existing studies. We will publish our findings in a peer-reviewed scientific journal.

Review Meta Analysis
Are mass-media campaigns effective in preventing drug use? A Cochrane systematic review and meta-analysis.
To determine whether there is evidence that mass-media campaigns can be effective in reducing illicit drug consumption and the intent to consume. ⋯ Studies were considerably heterogeneous in type of mass-media intervention, outcome measures, underlying theory, comparison groups and design. Such factors can contribute to explaining the observed variability in results. Owing to the risk of adverse effects, caution is needed in disseminating mass-media campaigns tackling drug use. Large studies conducted with appropriate methodology are warranted to consolidate the evidence base.
