Table 1. Results obtained for Groups A (uncensored) and B (censored) (data contained in Figure 1); the p-values are for two-tailed tests.

Group A (n = 20) Group B (n = 15)
Mean X-ray βL (Gy−2) 0.029 0.028
Mean neutron βH (Gy−2) 0.0789 0.075
Median X-ray βL (Gy−2) 0.022 0.024
Median neutron βH (Gy−2) 0.042 0.045
Ratio of means (βHL) 2.772 2.694
Ratio of medians (βHL) 1.886 1.875
“Best fit” linear equation (95% confidence intervals of slope parameter) βH = 3.18 βL [1.020, 5.335] βH = 1.82 βL [−0.410, 4.054]
Log-transformed paired t-test (two-tailed) p>0.4 p<0.01
Sign test p<0.05 p<0.01
