	HTLV Negative (n0 = 205)	HTLV-1 Positive (n = 62)	HTLV-1 infection PR (95%CI)
			Crude	Adjusted*
HPV infection with any type	60 (29.3%)	27 (43.6%)	1.60 (1.09–2.35)	2.10 (1.53–2.87)
High-risk HPV infection	46 (22.4%)	20 (32.3%)	1.45 (0.75–2.80)	1.93 (1.04–3.59)
Abnormal Papanicolaou †	24 (11.8%)	11 (18.0%)	1.44 (0.69–2.99)	1.39 (0.65–2.97)
LSIL or higher cytological abnormalities ‡	14 (6.9%)	7 (11.5%)	1.50 (0.68–3.33)	1.73 (0.68–4.44)

^*Adjusted for age, education, age of sexual partner, number of sexual partners within the last 12 months, and condom use at last sexual intercourse.

^†We included participants who had atypical squamous cells of undetermined significance (ASC-US), Atypical squamous cells - cannot exclude HSIL (ASC-H), Atypical glandular cells of undetermined significance (AGUS), Low-grade squamous intraepithelial lesion (LSIL), High-grade squamous intraepithelial lesion (HSIL), Squamous cell carcinoma, Adenocarcinoma in situ (AIS).

^‡We included participants who had LSIL, HSIL, Squamous cell carcinoma, and Adenocarcinoma in situ.
