FIGURE 5. Regression analysis of 18F-annexin V uptake in liver tissue versus percentage of TUNEL-positive nuclei in liver tissue slices (r2 = 0.89). Analysis included data from the 3 studies presented in Figure 4, as well as other studies (n = 13 animals total; each data point represents 1 animal). Error bars refer to SD of mean for percentage of TUNEL-positive values.
