^aOR = odds ratio (95% confidence interval). Weighted for sampling and adjusted for education.

^bCLR = confidence limit ratio, a measure of the precision of the odds ratio (upper confidence limit divided by lower confidence limit).

^cORs excluding women who answered “No” or “Don’t know” to having heard of HPV: 21.5 (95% CI: 9.1-50.9) for ever had HPV, 1.9 (95% CI: 0.9-4.0) for HPV causes cancer, 1.8 (95% CI: 0.7-4.4) for HPV is sexually transmitted, 2.1 (95% CI: 0.9-5.2) for HPV infection is common, 5.4 (95% CI: 1.4-20.3) for HPV often goes away on its own, 2.0 (95% CI: 0.6-6.2) for HPV causes abnormal pap, and 1.6 (95% CI: 0.5-4.7) for HPV does not affect ability to get pregnant.
