Logistic regression analysis of good to very good adherence to once-daily teriparatide

	Good to very good adherence (> 75%)	Crude OR (95% CI) [p value]	Adjusted OR (95% CI)	p value
Patient-support program enrollment = yes	428/790 (54.2%)	1.27 (1.01–1.60) [0.046]	1.44 (1.04–2.00)	0.030
Patient-support program enrollment = no	221/458 (48.3%)
Age (years)	–	–	0.99 (0.97–1.01)	0.345
Sex (male vs. female)	–	–	1.24 (0.68–2.25)	0.484
Smoking status (yes vs. no)	–	–	0.31 (0.14–0.68)	0.003
Previous therapy related to osteoporosis (yes vs. no)	–	–	1.36 (0.98–1.88)	0.064

The final model was adjusted for age (years), sex (male/female), smoking status (yes/no), and previous therapy related to osteoporosis (yes/no). Age and sex were included due to clinical importance and the other variables were identified using a stepwise backward elimination method
