Vitruvian plot: a visualisation tool for multiple outcomes in network meta-analysis

Abstract

OBJECTIVE: aims to facilitate communication of multiple outcomes from NMAs to patients and clinicians. METHODS: We developed this tool following the recommendations on the communication of benefit-risk information from the available literature. We collected and implemented feedback from researchers, statisticians, methodologists, clinicians and people with lived experience of physical and mental health issues. RESULTS: , which graphically presents absolute estimates and relative performance of competing interventions against a common comparator for several outcomes of interest. We use two alternative colour schemes to highlight either the strength of statistical evidence or the confidence in the evidence. Confidence in the evidence is evaluated across six domains (within-study bias, reporting bias, indirectness, imprecision, heterogeneity and incoherence) using the Confidence in Network Meta-Analysis (CINeMA) system. CONCLUSIONS: allows reporting of multiple outcomes from NMAs, with colourings appropriate to inform credibility of the presented evidence.
