Logarithms of Estimates of Residence Times τd After Diagnostic Administration of 131I
| Model | n | Arithmetic mean of ln τd | SD of ln τd | Effect of model | Effect of sampling |
|---|---|---|---|---|---|
| Monoexponential | 633 | −3.71 | 1.32 | ||
| Biphasic | 633 | −3.71 | 1.21 | P > 0.05 | |
| Monoexponential | 71 | −3.02 | 2.23 | P < 0.05 | |
| Biphasic | 71 | −2.88 | 1.68 | P > 0.05 | P < 0.01 |
Effect of model shows difference between monoexponential and biphasic models in each group of patients. Effect is evaluated by paired t test. Effect of sampling shows difference between 2 groups of patients with different sampling for monoexponential and alternative models. Effect is evaluated by standard t test for 2 arithmetic means.
