Review Meta Analysis
Selective serotonin reuptake inhibitors in childhood depression: systematic review of published versus unpublished data.
Questions concerning the safety of selective serotonin reuptake inhibitors (SSRIs) in the treatment of depression in children led us to compare and contrast published and unpublished data on the risks and benefits of these drugs. ⋯ Published data suggest a favourable risk-benefit profile for some SSRIs; however, addition of unpublished data indicates that risks could outweigh benefits of these drugs (except fluoxetine) to treat depression in children and young people. Clinical guideline development and clinical decisions about treatment are largely dependent on an evidence base published in peer-reviewed journals. Non-publication of trials, for whatever reason, or the omission of important data from published trials, can lead to erroneous recommendations for treatment. Greater openness and transparency with respect to all intervention studies is needed.

Review Meta Analysis
Insulin-like growth factor (IGF)-I, IGF binding protein-3, and cancer risk: systematic review and meta-regression analysis.
Insulin-like growth factor (IGF)-I and its main binding protein, IGFBP-3, modulate cell growth and survival, and are thought to be important in tumour development. Circulating concentrations of IGF-I might be associated with an increased risk of cancer, whereas IGFBP-3 concentrations could be associated with a decreased cancer risk. ⋯ Circulating concentrations of IGF-I and IGFBP-3 are associated with an increased risk of common cancers, but associations are modest and vary between sites. Although laboratory methods need to be standardised, these epidemiological observations could have major implications for assessment of risk and prevention of cancer.
