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

[Fan Li @FanLi90]

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 https://t.co/HjtOQ8xCrd

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.

2-weeks to go, 4th international conf. on the stepped wedge design. An exciting programme ahead, with Prof. Richard Hopper opening keynote speech: Untested geometries: What’s around the corner for the stepped wedge?

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.

[Centre for Advancing Health @Advancinghlth]

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

Super stoked to see this published! The preliminary work for this one dates back to my undergrad research (of course, with #MonicaTaljaard). Huge thanks to everyone involved!!

[Yongdong Ouyang @douyang3]

I am honoured and excited to be awarded the 2022 @CIHR_IRSC Health System Impact Postdoc Fellowship and work with @doctor_forster and #monicataljaard on the development of methodologies to evaluate and monitor innovation technologies at @OttawaHospital @OttMethodsCentr

[CIHR @CIHR_IRSC]

Today, the Honourable Jean-Yves Duclos announced 43 Health System Impact Fellows, an investment of more than $4.7M to address pressing health system priorities with evidence.
