Searching for Systematic Reviews of the Effects of Social and Environmental Interventions: A Case Study of Children and Obesity (Report)
INTRODUCTION Systematic reviews are an important part of the evidence base in public health. By locating and using all of the best available evidence, systematic reviews can overcome the potential for bias that is found in individual studies and provide reliable and accessible answers to questions about policy and practice. Systematic reviews also inform future research activity by identifying gaps and preventing duplication of effort. However, it can be difficult to know where to look for systematic reviews given the multiple research databases that index them and the fact that many are, at least initially, published as reports that may not be indexed in bibliographic databases.
