n, indicative of adjusted analyses.

n, number who used EC.

Factors with p < 0.10 in bivariate analyses that were controlled for in a multivariate model included: age, marital status, race/ethnicity, religion, poverty level income, MSA, condom use in past year, number of lifetime partners, number of partners in the past 12 months, and having had a Pap test.

Estimates are unstable as RSE > 30% and/or n_denominator < 50.
