Table 9. A: binary logistic regression for Death within 7 days (ED_d7). B: binary logistic regression for Death within 7 days (ED_d7).

A: binary logistic regression for Death within 7 days (EDd7)
Parameter	Comparison	n	OR	Lower CL	Upper CL	P
Early Death Score	Continuous parameter	52	2.772	1.384	5.552	0.004
Therapeutic leukapheresis	yes vs. no	52	0.853	0.105	6.920	0.882

9A: Therapeutic leukapheresis did not impact on the early death rate when the early death score was introduced as a continuous variable into the binary logistic regression. 9B: Therapeutic leukapheresis might lower the risk of early death in patients belonging to the LowR d7 group. Abbreviations: CL, confidence limit; n, number; OR, Odds Ratio.
