Table 3.

Association of relative telomere length with percent mammographic density and dense area before and after adjustment for risk factors and urinary MDA (n = 305).

Variable	Percent Mammographic Density (square root)^a			Dense Area (square root)^a			Non dense area (log)^a
Variable	Beta	SE	p value	Beta	SE	p value	Beta	SE	p value
RTL alone^b	0.82	0.71	0.25	0.82	0.73	0.26	−0.41	0.25	0.10
RTL adjusted for risk factors^c	−0.32	0.57	0.58	0.21	0.75	0.78	0.05	0.16	0.77
RTL adjusted for Risk Factors and MDA^d	−0.44	0.57	0.44	0.05	0.75	0.95	0.07	0.17	0.66
Interaction between RTL and MDA^e	3.54	1.06	0.001	2.82	1.41	0.05	−1.17	0.31	0.0002

RTL = relative telomere length; MDA = malondialdehyde; SE = standard error.

^aOutcome measure for regression analysis.

^bAdjusted for PCR batch only.

^cAdjusted for PCR batch and risk factors (from Table 2), except for MDA.

^dAdjusted for PCR batch, risk factors and MDA.

^eInteraction term for RTL*MDA, adjusted for main effects and risk factors.
