Overall survival
From figure panel A · validated against the values printed on the figure · curve source: pixel measurement confirmed by vision model
Reconstructed from the published curve. Median: AT not reached; NCRT not reached. Survival at 18 months: AT 81%; NCRT 81%. Hazard ratio AT vs NCRT 0.94 (95% CI 0.63–1.41).
| Arm | N | Events | Median (Months) |
|---|---|---|---|
| AT | 112 | 44 | not reached |
| NCRT | 118 | 50 | not reached |
- AT vs NCRT: reconstructed HR 0.94 (95% CI 0.63–1.41)
