Conditional logistic regression showing odds ratios (OR) and 95% confidence interval (CI) of in situ adenocarcinoma among women with HPV positive first and last smear.

Adenocarcinoma in situ
	First smear			Last smear
	Positive cases/controls	OR	95% CI	Positive cases/controls	OR	95% CI
HPV 16	23/3	11.0	2.6–46.8	35/5	32.0	4.2–227
HPV 18	26/1	26.0	3.5–192	34/0	∞	0-∞
HPV 16 /18	45/4	14.7	4.5–47.2	63/5	59.0	8.2–426
Non-16/18 HRHPV	8/3	3.5	0.7–16.8	11/4	2.8	0.9–8.6
LRHPV	4/3	1.3	0.3–6.0	2/4	0.5	0.1–2.7

Perfect separation, no estimate

HRHPV denotes High Risk HPV and LRHPV Low Risk HPV.
