FIGURE 3. Bland–Altman plots of hepatic 99mTc-mebrofenin uptake, expressed as percentage uptake per minute. (A) A plot of the mean of the repeated liver uptake function calculation on HBS in 45 studies (horizontal axis) vs. the differences in the repeated calculations (vertical axis). (B) A plot of the mean of FLR determination on HBS before and after surgery in 15 studies (horizontal axis) vs. the differences in the repeated measurements (vertical axis). The horizontal solid lines indicate the mean difference between the 2 calculations. The horizontal dashed lines indicate the 95% limits of agreement (mean ± 1.96 SD).
