Bayesian bivariate meta-analysis
WebMay 30, 2016 · Abstract Bivariate random-effects meta-analysis (BVMA) is a method of data synthesis that accounts for treatment effects measured on two outcomes. BVMA gives more precise estimates of the population mean and predicted values than two univariate random-effects meta-analyses (UVMAs). BVMA also addresses bias from incomplete … WebBivariate models fit using Bayesian and maximum likelihood methods produced almost identical summary estimates of sensitivity and specificity. The methods gave practically identical results in meta-analyses with moderate to large numbers of studies and when included studies had large sample sizes.
