Meta-Analyses of Glyphosate and Non-Hodgkin's Lymphoma: Expert Panel Conclusions and Recommendations

An expert panel was assembled to support a review of a series of recent publications using a modified Delphi format. These publications were scored based on a consideration of confidence in their methods, results, conclusions, and applicability to risk-based decision making. Mean confidence scores for the papers reviewed ranged from 53 to 74 (maximum score = 100), and key strengths and concerns were identified. This review highlights the need for transparency in meta-analyses. Different conclusions were reached in available meta-analyses because of varying criteria used to select studies, selection of different risk estimates within the same study, and study availability.
