Assessing Mediation in Cross‐Sectional Stepped Wedge Cluster Randomized Trials

Mediation analysis has been studied for independent data, but relatively little work has been done for correlated data observed under stepped wedge cluster randomized trials (SW-CRTs). Motivated by t...

A useful reminder of the original meaning of a "stepped wedge".

Stepped aluminium wedge that would be placed on the x-ray film to determine density of exposure and a fluoroscope that would let doctors view x-ray images 'in real time' without the use of film, I don't want to imagine the damage that could cause.

Super happy to say that my first Biometrics article was published this week!😃 Along with Fan Li, Monica Taljaard, & Denise Esserman, we derive sample size & power formula for cross-sectional stepped-wedge trials with time-to-event outcomes, & explored the impact of finite sample variance corrections

Power calculation for cross-sectional stepped wedge cluster randomized trials with a time-to-event endpoint

ABSTRACT. Stepped wedge cluster randomized trials (SW-CRTs) are a form of randomized trial whereby clusters are progressively transitioned from control to

Identifying Less Burdensome and More Cost‐Efficient Incomplete Stepped Wedge Designs for Continuous Outcomes Collected via Repeated Cross‐Sections

Stepped wedge trials can be costly and burdensome. Recent work has investigated the iterative removal of cluster-period cells from stepped wedge designs, producing a series of candidate incomplete de...
