Resumen
Abstract
Network meta-analysis can synthesize evidence from studies comparing multiple treatments for the same disease. Sometimes the treatments of a network are complex interventions, comprising several independent components in different combinations. A component network meta-analysis (CNMA) can be used to analyze such data and can in principle disentangle the individual effect of each component. However, components may interact with each other, either synergistically or antagonistically. Deciding which interactions, if any, to include in a CNMA model may be difficult, especially for large networks with many components. In this article, we present two Bayesian CNMA models that can be used to identify prominent interactions between components. Our models utilize Bayesian variable selection methods, namely the stochastic search variable selection and the Bayesian LASSO, and can benefit from the inclusion of prior information about important interactions. Moreover, we extend these models to combine data from studies providing aggregate information and studies providing individual patient data (IPD). We illustrate our models in practice using three real datasets, from studies in panic disorder, depression, and multiple myeloma. Finally, we describe methods for developing web-applications that can utilize results from an IPD-CNMA, to allow for personalized estimates of relative treatment effects given a patient's characteristics.
El proyecto COMPAR-EU ha recibido financiación del programa de investigación e innovación Horizont 2020 de la Unión Europea en virtud del acuerdo de subvención nº 754936.
Tenga en cuenta que ésta es la versión beta de la plataforma COMPAR-EU. Ahora incluye los resultados completos para Diabetes y durante todo el verano de 2022 se completarán los resultados para Obesidad, EPOC e Insuficiencia Cardíaca. La plataforma también se ampliará y mejorará en los próximos meses.
