Comparing the Performance of Statistical Adjustment Methods By Recovering the Experimental Benchmark from the REFLUX Trial
Luke Keele, Stephen O'Neill, Richard Grieve
Much evidence in comparative effectiveness research is based on observational studies. Researchers who conduct observational studies typically assume that there are no unobservable…
Non-compliance and missing data in health economic evaluation
Karla DiazOrdaz, Richard Grieve
Health economic evaluations face the issues of non-compliance and missing data. Here, non-compliance is defined as non-adherence to a specific treatment, and occurs within randomis…
Instrumental variable approaches for estimating complier average causal effects on bivariate outcomes in randomised trials with non-compliance
Karla DiazOrdaz, Angelo Franchini, Richard Grieve
In Randomised Controlled Trials (RCT) with treatment non-compliance, instrumental variable approaches are used to estimate complier average causal effects. We extend these approach…
A comparison of multiple imputation methods for bivariate hierarchical outcomes
Karla Diaz-Ordaz, Michael G. Kenward, Manuel Gomes +1
Missing observations are common in cluster randomised trials. Approaches taken to handling such missing data include: complete case analysis, single-level multiple imputation that…
