We performed three systematic reviews on methods for: network meta-analysis (NMA) individual participant data (IPD) meta-analysis mathematical modelling to predict real-world effectiveness based on evidence from randomized controlled trials (RCTs) Our aim was to identify and describe state-of-the-art methods in these three research areas, to summarize methodological challenges and limitations and to give recommendations on the use of the discussed methods. All three reviews were accepted for publication in the Research Synthesis Methods journal The research leading to these results has received support from the Innovative Medicines Initiative Joint Undertaking under grant agreement no [115303], resources of which are composed of financial contribution from the European Union ’ s Seventh Framework Programme (FP7/2007-2013) and EFPIA companies ’ in kind contribution. 7 www.imi.europa.eu

• Guidance: Presented the advantages and limitations of alternative approaches. Discussed in depth methods to assess the validity of the underlying assumptions Provided technical details regarding a series of special issues: network meta- regression, accounting for the risk of bias, multiple outcomes and repeated measures, defining the number of nodes, planning future studies, etc. Listed software tools for fitting NMA and for assessing its assumptions. • Our review constitutes the most comprehensive collection of methods for NMA to date and can be a valuable tool for both experienced researchers as well as researchers taking their first steps in NMA Efthimiou, O., Debray, T.
