Table 5

Multivariate Cox model for OS and RFS risk factors of MPAL, Ly⁺AML, and Ly⁻AML patients.

Risk factors	OS			RFS
	HR	95% CI	P value	HR	95% CI	P value
WBC	1.003	1.001–1.006	0.009	—	—	—
Chromosome karyotype
Normal	1.000	—	—	1.000	—	—
Complex	2.068	1.284–3.330	0.003	2.140	1.331–3.441	0.002
Abnormal	1.735	0.995–3.023	0.052	1.498	0.865–2.594	0.149

HR: hazard ratio; CI: confidence interval; WBC: white blood cell; OS: overall survival; RFS: relapse-free survival.
