Multivariate analysis of risk factors
| Variable . | Overall survival . | Event-free survival . | ||
|---|---|---|---|---|
| HR (95% CI) . | P . | HR (95% CI) . | P . | |
| WBC at diagnosis, ×109/L (less than 30, n=42; more than 30, n = 36; na = 1) | 1.92 (1.02-3.61 | .05 | 1.79 (0.98-3.29) | .06 |
| Prior radiation therapy (yes, n = 13; no, n = 61; na = 5) | 1.44 (0.67-3.12) | .35 | 1.35 (0.64-2.86) | .43 |
| Disease status at HCT (CR1, n = 49; beyond CR1, n = 30) | 2.14 (1.09-4.15) | .03 | 1.99 (1.06-3.74) | .03 |
| Acute GVHD (yes, n = 26; no, n = 51) | 1.77 (0.95-3.32) | .07 | (1.01-3.36) | .05 |

HR indicates hazard ratio; WBC, white blood cell count; HCT, hematopoietic cell transplantation; and GVHD, graft-versus-host disease.
