TABLE 3.

Parameter Estimates (with 95% CI) for the Multiplicative Excess Relative Risk (ERR) Model (Eq. 1) for Plutonium and External Dose by Gender

	Males	Females
Baseline relative risk for smokers	10 (6.4 to 18)	5.7 (2.3 to 12)
Baseline relative risk for unknown smoking status	5.7 (3.1 to 11)	1.9 (0.6 to 4.7)
Plutonium ERR per Gy at age 60	7.4 (5.0 to 11)	24 (11 to 56)
P for gender difference in plutonium ERR per Gy	< 0.001
Gender ratio (F:M)	3.3 (1.4 to 7.9)
Attained age (power)^a	−3.1 (−5.4 to −0.8)
External dose ERR per Gy	0.13 (−0.04 to 0.38)
