The role of assignment in defining and identifying causal effects in randomized trials
Issa J. Dahabreh, Lawson Ung, Miguel A. Hernán +1
In randomized trials, the per-protocol effect, that is, the effect of being assigned a treatment strategy and receiving treatment according to the assigned strategy, is sometimes t…
Generalizing and transporting causal inferences from randomized trials in the presence of trial engagement effects
Lawson Ung, Tyler J. VanderWeele, Issa J. Dahabreh
Trial engagement effects are effects of trial participation on the outcome that are not mediated by treatment assignment. Most work on extending (generalizing or transporting) caus…
Robust integration of external control data in randomized trials
Rickard Karlsson, Guanbo Wang, Piersilvio De Bartolomeis +2
One approach for increasing the efficiency of randomized trials is the use of "external controls" -- individuals who received the control treatment studied in the trial during rout…
Identification strategies for combining an experimental study with external data
Lawson Ung, Guanbo Wang, Sebastien Haneuse +2
There is increasing interest in combining information from experimental studies, including randomized and single-group trials, with information from external experimental or observ…
Efficient estimation of subgroup treatment effects using multi-source data
Guanbo Wang, Alexander Levis, Jon Steingrimsson +1
Investigators often use multi-source data (e.g., multi-center trials, meta-analyses of randomized trials, pooled analyses of observational cohorts) to learn about the effects of in…
Causal inference under transportability assumptions for conditional relative effect measures
Guanbo Wang, Alexander Levis, Jon Steingrimsson +1
When extending inferences from a randomized trial to a new target population, the transportability condition for conditional difference effect measures is invoked to identify the m…
