Randomization inference for stepped-wedge designs with noncompliance with application to a palliative care pragmatic trial
Jeffrey Zhang, Zhe Chen, Xinyuan Chen +5
While palliative care is increasingly commonly delivered to hospitalized patients with serious illnesses, few studies have estimated its causal effects. Courtright et al. (2016) ad…
Time-varying treatment effect models in stepped-wedge cluster-randomized trials with multiple interventions
Zhe Chen, Wei Wang, Yingying Lu +4
The traditional model specification of stepped-wedge cluster-randomized trials assumes a homogeneous treatment effect across time while adjusting for fixed-time effects. However, w…
On Anticipation Effect in Stepped Wedge Cluster Randomized Trials
Hao Wang, Xinyuan Chen, Katherine R. Courtright +4
In stepped wedge cluster randomized trials (SW-CRTs), the intervention is rolled out to clusters over multiple periods. A standard approach for analyzing SW-CRTs utilizes the linea…
Assessing treatment effect heterogeneity in the presence of missing effect modifier data in cluster-randomized trials
Bryan S. Blette, Scott D. Halpern, Fan Li +1
Understanding whether and how treatment effects vary across subgroups is crucial to inform clinical practice and recommendations. Accordingly, the assessment of heterogeneous treat…
