Table 1.

Table shows the treatment effect as the tumor volume for a treatment relative to the tumor volume of a reference treatment, averaged over a time period (Eq. 1).

Uncertainties are given as 95% confidence intervals. Reference treatments are PBS or X-rays. p-values were calculated as Fishers combined probability test (within a time period) where individual p-values for each time point used in the calculation were found by paired t-test. p-values < .05 are marked with * and p-values < .01 are marked with **.
