Webinar on ‘Stepped Wedge Trials’

Dr. Li

Dr. Fan Li

The Office of Disease Prevention (ODP) will hold a Methods: Mind the Gap webinar with Dr. Fan Li on the overview of statistical models for the design and analysis of stepped wedge cluster randomized trials. The webinar will take place on Tuesday, July 14 at 1 p.m.

The stepped wedge cluster randomized design has received increasing attention in pragmatic clinical trials and implementation science research. The key feature of the design is the unidirectional crossover of clusters from the control to intervention conditions on a staggered schedule, which induces confounding of the intervention effect by time.

Li is an assistant professor of biostatistics at the department of biostatistics, Yale University School of Public Health. A biostatistician, he works with researchers from a variety of medical specialties in the design and analysis of cluster randomized trials, individually randomized clinical trials and observational studies.

Registration is required at The webinar will be recorded and available on the ODP website within about a week.
