Network meta-analysis incorporating randomized controlled trials and non-randomized comparative cohort studies for assessing the safety and effectiveness of medical treatments: challenges and opportunities
We review issues in network meta-analysis, specifically related to the incorporation of observational data.
Statistical power in parallel group point exposure studies with time-to-event outcomes: an empirical comparison of the performance of randomized controlled trials and the inverse probability of treatment weighting (IPTW) approach
We compare the statistical power of an observational study using an IPTW design with that of a randomized controlled trial.
Contour plot assessment of meta-analyses: robust association of statins-use and acute kidney injury risk
We propose an extended contour approach for the graphical assessment of the robustness of meta-analyses results with applications to data on statins use and kidney injury.
On the role of marginal confounder prevalence – implications for the high-dimensional propensity score algorithm
We apply the law of total probability in conjunction with an established bias formula to derive and illustrate relative bias boundaries with respect to marginal confounder prevalence.
We review issues with regard to the use of the odds ratio and collapsibility, and demonstrate the relation between collapsibility and effect modification.
