NOTE: Excludes women reporting hysterectomy, women who report an abnormal Pap in last 3 years, and women who reported their last Pap was not part of a regular screening examination. To construct our multivariable model, we conducted a separate bivariate analysis comparing last Pap test reported within 12 versus 13–36 months (data not shown). Statistically significant variables with P < 0.05 from this separate bivariate analysis were included in the multivariate analysis. as covariates.

^aAmong women who have ever had a Pap, odds of reporting most recent Pap within 12 months, compared to all other intervals (>1–2, >2–3, >3–5, >5years).

^bBecause the confidence interval does not overlap the referent group, we ran a contrast test for 18–21 versus 26–29 and the Wald-F P = 0.036.

^cMedicare, Medicaid (Military defined as private).

^dPills, implants, shots.

^eResponse “Did not see a doctor on the past 12 months” included in analysis, but suppressed in this table.
