Association of thiamine intake with different types of HPV infection.

Exposure	Model 1 β (95% CI)	Model 2 β (95% CI)	Model 3 β (95% CI)	GAM model β (95% CI)
High-risk HPV infection	n=10565	n=9410	n=3187	n=3187
Thiamine intake (mg) (log2 transform)	0.83 (0.79, 0.88)	0.89 (0.84, 0.94)	0.91 (0.82, 1.01)	0.92 (0.83, 1.03)
Low-risk HPV infection	n=10495	n=9537	n=3174	n=3174
Thiamine intake(mg) (log2 transform)	0.82 (0.78, 0.86)	0.86 (0.81, 0.91)	0.84 (0.76, 0.93)	0.85 (0.76, 0.94)

Model 1 – no covariates were adjusted; Model 2 – only sociodemographic variables were adjusted (body mass index, age, education, marital status, and ethnicity); Model 3 – all covariates presented in Table 1 were adjusted; GAM Model – all continuous variables in the covariates were adjusted as smooth.
