Power for each method by true cell proportion (θ) when the overall proportion (μ) is 1/1000 and the cell population size (ni+) is 10000, without consideration of R1 and R2. The solid and short dashed lines represent the BN method when the cluster sizes are 1.25 and 1.5 times the expected overall rate, respectively. The long dashed and dotted lines represent the CI method when the observed cell proportions (ci+/ni+) are 0.96θ and 1.1θ, respectively.
