Fig. 7From: The impact of iterative removal of low-information cluster-period cells from a stepped wedge designPrecision loss (top panel) and power (bottom panel) corresponding to designs obtained through the iterative removal process, indicated by the removal percentage of cluster-period cells, for the discrete-time decay model with \(\rho =0.05\) and \(r=0.95\), and a standardised effect size of 0.2Back to article page
