From: The power of FDG-PET to detect treatment effects is increased by glucose correction using a Michaelis constant

Figure 4

Power improvement. Left panel: power improvement in using M R gluc max compared to K i when n = 8, δ = 0.2 as a function of the CV in K i for the 66 studies of Table  2. Right panel: scatter plot estimates of the sample size required to reach 80% statistical power as a function of the CV in K i. The power curve for K i is shown in black and for M R gluc max , in blue. The parameter values and power improvement of the three simulation settings S1, S2, and S3 are depicted for reference in each plot.
