Power analysis for cluster randomized trials with continuous co-primary endpoints
Siyun Yang, Mirjam Moerbeek, Monica Taljaard +1
Pragmatic trials evaluating health care interventions often adopt cluster randomization due to scientific or logistical considerations. Previous reviews have shown that co-primary…
On the mixed-model analysis of covariance in cluster-randomized trials
Bingkai Wang, Michael O. Harhay, Jiaqi Tong +3
In the analyses of cluster-randomized trials, mixed-model analysis of covariance (ANCOVA) is a standard approach for covariate adjustment and handling within-cluster correlations.…
Estimating the natural indirect effect and the mediation proportion via the product method
Chao Cheng, Donna Spiegelman, Fan Li
The natural indirect effect (NIE) and mediation proportion (MP) are two measures of primary interest in mediation analysis. The standard approach for estimating NIE and MP is throu…
Power considerations for generalized estimating equations analyses of four-level cluster randomized trials
Xueqi Wang, Elizabeth L. Turner, John S. Preisser +1
In this article, we develop methods for sample size and power calculations in four-level intervention studies when intervention assignment is carried out at any level, with a parti…
Constrained randomization and statistical inference for multi-arm parallel cluster randomized controlled trials
Yunji Zhou, Elizabeth L. Turner, Ryan A. Simmons +1
A practical limitation of cluster randomized controlled trials (cRCTs) is that the number of available clusters may be small, resulting in an increased risk of baseline imbalance u…
Retrospective causal inference via matrix completion, with an evaluation of the effect of European integration on cross-border employment
Jason Poulos, Andrea Albanese, Andrea Mercatanti +1
We propose a method of retrospective counterfactual imputation in panel data settings with later-treated and always-treated units, but no never-treated units. We use the observed o…
