Cinzia Del Giovane is a Senior Researcher at the Statistics Unit, Department of Medical and Surgical Sciences for Children and Adults, University-Hospital of Modena and Reggio Emilia, Italy. She is a statistical advisor for Cochrane Italy and member of the Cochrane Statistics Methods Group. Cinzia has extensive experience in the methodology of systematic reviews, meta-analyses and especially network meta-analyses. She has co-authored nine publications within the Cochrane Library and more than 20 publications that included network meta-analysis since 2016. In all these projects, she provided methodological support in study design and performed the network meta-analysis. As well as contributing to the development of a new framework for determining confidence in the network meta-analysis results, Cinzia also helped inform the development of the web application based on this framework, CINeMA, which facilitates the assessment process and hence determines the degree of confidence one can place on network meta-analysis treatment effects. Since 2011, Cinzia has actively participated in the Cochrane Colloquiums by presenting workshops, oral papers and posters. She also coordinated a scientific group at the University of Modena and Reggio Emilia, and led lectures on their post-graduate course on “Cochrane Systematic Reviews and Meta-Analyses”.
