Table 3.

Hazard ratio of hematologic malignancies in patients with myeloproliferative neoplasms (MPN) compared to matched controls, stratified by MPN subtype. MPN=myeloproliferative neoplasm, PV=polycythemia vera, ET=essential thrombocythemia, PMF=primary myelofibrosis, MPN-U=myeloproliferative neoplasm, unclassifiable, AML=acute myeloid leukemia, HR=hazard Ratio, CI=confidence interval, n=number

MPN subtype	AML HR (95% CI) n = 278	Lymphoma HR (95% CI) n = 90	Multiple myeloma HR (95% CI) n = 16
All MPN	46.0 (32.6 - 64.9)	2.6 (2.0 – 3.3)	1.7 (1.0 - 3.0)
PV	38.1 (23.5 - 62.0)	1.9 (1.3 - 2.8)	1.6 (0.7 - 3.5)
ET	26.1 (13.4 - 50.9)	2.3 (1.3 - 3.9)	1.4 (0.5 - 3.6)
PMF	99.2 (41.0 - 240.1)	6.0 (3.4 - 10.8)	9.0 (1.8 - 44.0)
