I am honoured and excited to be awarded the 2022 CIHR Health System Impact Postdoc Fellowship and work with Alan Forster and #monicataljaard on the development of methodologies to evaluate and monitor innovation technologies at The Ottawa Hospital Ottawa Methods Centre


For sample sizes in RCTs, many use a minimum important difference. But, argues CHÉOS Head of #Biostatistics Dr. Hubert Wong in General Medicine and Medical Evidence @ BMC, we should use a realistic estimate of the true benefit, or we will fail to meet target power. #statstwitter trialsjournal.biomedcentral.com/articles/10.11…



My recent article with Dr. Manisha Kulkarni (UOttawa), Dr. Natacha Protopopoff (LSHTM), Fan Li, and Dr. Monica Taljaard (OHRI) on complex intracluster correlation structure for CRT in malaria trials Ottawa Methods Centre School of Epidemiology and Public Health doi.org/10.1186/s12874…


Repost (accidentally deleted my previous post) My recent work with @karlahemming(@UoB_IAHR), Fan Li(Yale Biostatistics), and #monicataljaard (rakesh School of Epidemiology and Public Health Ottawa Methods Centre) on how to estimate ICC when planning a multiple-period cluster randomized trials (Shinyapp included)


I am looking for a full-time Biostatistics Postdoctoral Associate to join my team in 2024, with a flexible start date. The candidate will work on developing methods for cluster randomized trials & stepped wedge designs. Position details m.yale.edu/b7s4 via Yale School of Public Health

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 Pascale 🌱 with @Marym_Ryan Yongdong Ouyang Can Meng Tony Guangyu TONG and others.



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? Stepped Wedgehog Free registration: x.com/MonaKanaan3/st…


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 Yongdong Ouyang journals.sagepub.com/doi/10.1177/09…

Meet IMPaCT Fellow Cal Robinson ! Through his research, Cal aspires to advance the evidence-based treatment of pediatric kidney diseases, prevent adverse long-term outcomes, and minimize disease burden. Learn more about Cal’s project here: impactrials.ca/cal-robinson


Curious about extremely small stepped wedge cluster randomized trials (SW-CRTs)? Our latest paper, led by Tony Guangyu TONG, explores the landscape of published SW-CRTs with <= 6 clusters. Take a look at what we found! journals.sagepub.com/doi/10.1177/17… Colin Begg Stepped Wedgehog

New article by Tony Guangyu TONG and others reviews key practices in designing and analyzing these small-scale #ClinicalTrials, offering insights for researchers. Access at doi.org/10.1177/174077… #ResearchMethods #Biostatistics


Bothered by the proliferation of stepped-wedge clinical trials with very few clusters? Guanyu Tong and colleagues study this issue and offer advice. Tony Guangyu TONG Yale Cardiology Yale Biostatistics SCTorg Monica Taljaard
