After adjusting for confounders, logistic regression revealed that co-infection of HPV16 with low-risk HPV genotypes reduced the risk of progression to HSIL+ compared to HPV16 monoinfection (<i>p</i> &lt; 0.05). Similarly, co-infections involving HPV33 or HPV58 (regardless of high/low-risk partners) were associated with lower HSIL+ risk (all <i>p</i> &lt; 0.05).

Co-infection with low-risk HPV genotypes attenuates HSIL+ risk in HPV16-infected individuals, and HPV33/58 co-infections (with any genotype) exhibit protective effects. Our study suggests that HPV31-associated risk might remain unaffected by co-infection, suggesting genotype-specific biological interactions.
