Abstract

Meta-analysis is an essential methodology for synthesizing evidence, particularly in the biomedical and social sciences. Quantitative research synthesis is frequently used to accumulate evidence about questions of interest; it can also be used to investigate the generalizability of research results and to investigate alternative explanations for observed associations. Some even argue that meta-analysis can be used to establish causal effects. In this talk, we discuss the role of research synthesis in the process of scientific explanation and consider the strengths and weaknesses of evidence generated from research synthesis. As a case study to help illustrate some of these issues, we consider the evidence from a meta-analysis of randomized controlled trials that the FDA used to inform their decision to issue a black box warning for the use of antidepressants in children. This is joint work with Kelly Kelleher, Elly Kaizar, and Howard Seltman.
