Abstract: Many individually randomized group treatment (IRGT) trials randomly assign individuals to study arms but deliver treatments via shared agents, such as therapists, surgeons, or trainers. Post‐randomization interactions induce correlations in outcome measures between participants sharing… read more here.

Abstract: In cluster randomized trials, the introduction of the intervention can be staggered in different clusters, leading to a stepped wedge design. This strategy can lead to gains in efficiency, which might also translate to the… read more here.
