Abstract
Background:
There is increasing evidence to suggest that nutrition can impact both short- and long-term health outcomes. The right nutrition at the right time can help ensure clinically relevant benefits. Systematic reviews and meta-analyses have become more widely accepted by clinicians, researchers and policy makers as a useful tool to critically assess the totality of evidence in nutrition. However, little work has been done to identify the great scientific output in this field. Citation analyses has been regarded as a useful method to evaluate the impact of articles in medical field.
Objectives:
We aimed to identify and analyze the most highly cited systematic reviews and meta-analyses, further analyses the main features of 100 most-cited articles in the field excluding the methodology studies.
Methods:
A search was conducted to identify all nutritional systematic reviews and meta-analyses ever been published in the Web of Science from inception to March 2020. Using the Clarivate Analytics ‘Web of Science Core Collection (WoSCC)’, the selected articles were ranked in descending order on the basis of their citation counts. Each article on the list was reviewed by reading the abstract first by two reviewers independently, methodological studies were excluded, and finally, a unanimous decision was made on the list of the top 100 most-cited publications from the systematic reviews and meta-analyses that were included. VOSviewer (Centre for Science and Technology Studies, Leiden University, Leiden, The Netherlands) and CiteSpace (Chaomei Chen, China) were used to make visualization mapping in this paper.
Results:
This study is ongoing, and results will be presented at the Cochrane Colloquium as available.
