Leukocyte telomere length and its association with mammographic density and proliferative diagnosis among women undergoing diagnostic image-guided breast biopsy

Table 2 Associations of relative leukocyte telomere length (LTL) with proliferative diagnoses

	Women with proliferative diagnosis¹ (N = 141) Mean (SD)	Women with non-proliferative diagnosis² (N = 54) Mean (SD)	OR (95 % CI)^*	OR (95 % CI)^**
Relative LTL	1.6 (0.9)	1.2 (0.6)	2.46 (1.47, 4.42)	2.41 (1.43, 4.38)
	Women with in situ or invasive cancer diagnosis (N = 31) Mean (SD)	Women with non-proliferative diagnosis² (N = 54) Mean (SD)
Relative LTL	1.7 (1.1)	1.2 (0.6)	1.98 (1.07, 4.14)	1.70 (0.86, 3.76)

SD Standard deviation
¹Diagnosis of hyperplasia, in-situ or invasive carcinomas
²Diagnosis of benign or other discrete non-proliferative diagnosis
^*Adjusted for age (continuous) and BMI (continuous)
^**Adjusted for age (continuous), BMI (continuous), age at first birth (nulliparous/<30/≥30) and menopausal hormone therapy (premenopausal/postmenopausal ever/ postmenopausal never)
