	n (%)			Ordinal logistic regression	OR (95% CI)
DNA fragmentation rate <14.0%	110 (72.8%)	93 (67.9%)	22 (51.2%)	Univariate	1 (reference)	1.3 (0.8, 2.1)	2.4 (1.2, 4.7)
DNA fragmentation rate 14.0%–29.9%	30 (19.9%)	30 (21.9%)	16 (37.2%)	Adjusted	1 (reference)	1.4 (0.8, 2.4)	2.5 (1.2, 5.1)
DNA fragmentation rate ≥30%	11 (7.3%)	14 (10.2%)	5 (11.6%)

Abbreviation: BMI, body mass index.

ORs for moving from one DNA fragmentation category to the next. Results are presented as unadjusted, and adjusted for age and tobacco use.
