From: The impact of iterative removal of low-information cluster-period cells from a stepped wedge design
Top: A complete standard stepped wedge design schematic with four clusters (rows) and five periods (columns). Bottom: An incomplete stepped wedge design schematic with four clusters and spanning five periods. Cluster-period cells contain either 0, indicating the control condition, or 1, indicating the intervention condition. Blank areas within the schematic indicate cluster-periods in which no measurements are taken
