Risk of second primary malignancies in a population-based study of adult patients with essential thrombocythemia

Table 2 Age standardized cause-specific survival rates of the study population

Survival at defined time period	Entire cohort	Male	Female	Patients < 50 yr	Patients ≥ 50 yr
12 mo	99.10%	98.80%	99.30%	99.90%	98.90%
24 mo	98.30%	97.80%	98.70%	99.80%	97.90%
36 mo	97.20%	96.20%	97.90%	99.70%	96.50%
48 mo	96.10%	94.80%	96.90%	99.70%	95.00%
60 mo	94.90%	93.10%	96.00%	99.40%	93.50%

The percentage indicates cause-specific survival of specified population at defined time period.
