Table 3 Bayesian hierarchical IPD-NMA models described in the identified methodological articles

From: A scoping review of indirect comparison methods and applications using individual patient data

Model 1-stage or 2-stage process Format of data Study design Type of data Effect size Assumptions for treatment by covariate interactions
Donegan et al. [6] 1-stage IPD only RCTs Dichotomous Odds ratio No interactions; exchangeable treatment by covariate interactions; common treatment by covariate interactions
Donegan et al. [42] 1-stage IPD+AD and IPD only RCTs Dichotomous Odds ratio No interactions; independent treatment by covariate interactions; exchangeable treatment by covariate interactions; common treatment by covariate interactions
Hong et al. [43] 1-stage IPD only RCTs Continuous Mean difference Exchangeable treatment by covariate interactions
Jansen [41] 1-stage IPD+AD and IPD only RCTs Dichotomous Odds ratio Exchangeable treatment by covariate interactions; common treatment by covariate interactions
Saramago et al. [10] 1-stage IPD+AD and IPD only Cluster and individual allocation trials Dichotomous Odds ratio Independent treatment by covariate interactions; exchangeable treatment by covariate interactions; common treatment by covariate interactions
Saramago et al. [44] 1-stage IPD+AD RCTs Time-to-event Hazard ratio Common treatment by covariate interactions
Thom et al. [45] 1-stage IPD+AD RCTs and single-arm observational studies Continuous Mean difference Independent treatment by covariate interactions
