Univariate and multivariate models of the association between specific vaginal practices at baseline and follow-up, and consistent diaphragm/gel use among MIRA Intervention Group participants (2,438 participants; 12,853 persons-visits)

Vaginal practices	Univariate analyses				Multivariate analyses
	OR estimate	Lower 95% CI	Upper 95% CI	Chi-square P-value	AOR estimate	Lower 95% CI	Upper 95% CI	Chi-square P-value

Baseline intravaginal wiping	0.99	0.88	1.12	ns	na
Baseline intravaginal insertion	1.12	0.97	1.29	ns	na

Intravaginal washing at follow-up*	0.83	0.76	0.92	0.0003	0.88	0.79	0.98	0.0147
Intravaginal wiping at follow-upa	0.86	0.80	0.93	<0.0001	0.90	0.83	0.97	0.0083
Intravaginal insertion at follow-upa	0.80	0.72	0.90	<0.0001	0.83	0.74	0.93	0.0014

^aIn univariate analyses, washing, wiping and insertion at follow-up visits were controlled for at study site

Multivariate analyses controlled for baseline factors and potential confounders that remained significant at P < 0.05: study site, age, educational status, women’s behavioral risk, high risk partner
