Kaplan-Meier Analysis
| Tumor group | Treatment dose | n | Events | Median survival (95% CI) [days] | Restricted mean** survival ± standard error (days) |
|---|---|---|---|---|---|
| 9L | Untreated control | 30 | 30 | 9 [9,11] | 10 ± 1 |
| 20 Gy | 22 | 17 | 27 [23,63] | 65 ± 16 | |
| 25 Gy | 64 | 33 | 119 [26, >200] | 111 ± 11 | |
| U-251N | Untreated control | 23 | 23 | 26 [20,35] | 26 ± 1 |
| 20 Gy | 43 | 16 | > 200 [196, >200] | 157 ± 10 |
Notes. Survival is stated as median survival time for “n” animals in days based on events of death or COVID censorship, with 95% confidence limits in brackets and restricted mean survival in days plus or minus its standard error.
**
Restricted with an upper limit of survival of 200 days.
