Association Between Baseline High-Risk Human Papillomavirus Types and Progression to High-Grade Squamous Intraepithelial Lesions at Follow-up Visit

HPV Status at Baseline Visit		No.	Progression to HSIL at Follow-up Visit, No. (%)
Type 16/18	Other hrHPV^a	No.	Progression to HSIL at Follow-up Visit, No. (%)
_	_	15	1 (7)
+	+	66	44 (67)^b
+	_	8	4 (50)
_	+	79	20 (25)
Total		168	69 (41)

Abbreviations: HPV, human papillomavirus; hrHPV, high-risk human papillomavirus; HSIL, high-grade squamous intraepithelial lesion.

^aOther hrHPV types: 31/33/35/39/45/51/52/56/58/59/66/68.

^bHPV-16/18–positive patients had a significantly greater probability of progressing than patients with other types or negative hrHPV at baseline (67%, 25%, and 7%; P < .001).
