Table 2. Multivariate analysis of the influence of experimental settings on clonogenic survival.
Parameter | SF2 | SF4 | SF6 | SF8 | D10 | D50 |
---|---|---|---|---|---|---|
Radiation type* | 0.63 | 0.49 | 0.57 | 0.47 | 0.95 | 0.34 |
Dose rate | 0.50 | 0.24 | 0.69 | 0.53 | 0.95 | 0.77 |
Timing for cell seeding** | 0.04 | 0.63 | 0.47 | 0.24 | 0.83 | 0.91 |
The influence of radiation type, dose rate, and timing of cell seeding on SF2, SF4, SF6, SF8, D10, or D50 was examined by multiple linear regression. P values are shown. *X-rays vs. γ-rays; **before irradiation vs. after irradiation.
