Bothered by the proliferation of stepped-wedge clinical trials with very few clusters? Guanyu Tong and colleagues study this issue and offer advice. @TonyGuangyuTONG @YaleCardiology @ysphbiostat @SCTorg @MonicaTaljaard

Curious about extremely small stepped wedge cluster randomized trials (SW-CRTs)? Our latest paper, led by @TonyGuangyuTONG, explores the landscape of published SW-CRTs with <= 6 clusters. Take a look at what we found!

Worry about random-effects misspecification in stepped wedge trials? Then consider the cluster-robust sandwich variance estimator as part of the primary analysis. We offer some practical recommendations in this simulation study led by @douyang3 journals.sagepub.com/doi/10.…

With #TargetTrial emulation becoming increasingly popular, it's important to understand what it can and cannot do.
In this new podcast, I discuss how target trial emulation can 1) improve causal inference from observational data, and 2) extend inferences from randomized trials.
Professor @_MiguelHernan of @HarvardChanSPH discusses "Target Trial Emulation: A Framework for Causal Inference From Observational Data" with JAMA Statistical Editor Roger J. Lewis. ja.ma/3QupTYZ

Wondering how well we adhered to key recommendations when working with stepped-wedge cluster randomized trials in the past half decade? Check out this most recent systematic review led by @PascaleNevins with @Marym_Ryan @douyang3 @CanMeng47 @TonyGuangyuTONG and others.

For sample sizes in RCTs, many use a minimum important difference. But, argues CHÉOS Head of #Biostatistics Dr. Hubert Wong in @MedicalEvidence, we should use a realistic estimate of the true benefit, or we will fail to meet target power. #statstwitter
