Table 4 Comparison of false positive and false negative rates between homogenized setup and pseudo-heterogenized setup

From: Impact of inherent variability and experimental parameters on the reliability of small animal PET data

  Homogenized test groups Heterogenized test groups (α = 0.05) Heterogenized test groups (α = 0.05)
False positive rate (%) 9 ± 5 2 ± 3 6 ± 6
False negative rate (%) 63 100* 63
  1. *P < 0.05. For heterogenized groups, α was adapted from 0.05 to 0.38 in order to achieve the same study power as in the homogenized setup; n = 4; mean of false positive/negative rates ± SEM in percent.
