Abstract: What was the project about?In a stepped-wedge cluster randomized trial, or SW-CRT, researchers compare new treatments to standard treatments in groups of patients, such as patients at different clinics, to look at the treatments' effectiveness.They assign groups by chance to switch from the standard to new treatment at different time points until all groups have received the new treatment.The different time points to switch treatments are called steps. What were the limits of the project?The research team tested the methods with SW-CRTs that group patients at a single level, such as by clinic.The study didn't test the methods for SW-CRTs that group patients at more than one level, such as by doctors within clinics.Future research could apply the methods to SW-CRTs that group patients at more than one level. How can people use the results?Researchers can use these results to design and analyze SW-CRTs.
