Research in Context is a structured summary that editors at The Lancet’s journals ask all authors to provide when submitting an original research article. This summary is assessed by the editorial teams and is also peer-reviewed to ensure its integrity and accuracy. Because these summaries are written by the authors, they give the researchers' own account of where the study fits in the overall medical landscape. Each summary has three sections:
Evidence before this study. The authors describe the research that existed before they began. This includes the sources they searched (such as databases, journals, or reference lists), the criteria used to include or exclude studies, the dates and languages covered, the search terms, the quality or risk of bias of the evidence, and, where appropriate, a pooled estimate from a meta-analysis.
Added value of this study. The authors explain how their findings contribute to what was already known.
Implications of all the available evidence. The authors state what the new findings, taken together with the existing evidence, mean for clinical practice or policy, and for future research.
Per the journals’ format, Research in Context summaries do not include references, and key studies mentioned are cited in the full article available at www.thelancet.com
