Multivariable linear regression models were employed for the whole population, female population, and sexually active population, including the knowledge percentage score as an outcome variable and controlled for the following variables: age, gender, year of enrollment, smoking habits, province of residency, received an invitation to undergo vaccination (HPV invitation), number of sexual partners over the last year, obi-gyn visit (only in the female population), and the use of condoms (only in the sexually active population). Results are presented as a regression coefficient (Coef) and 95% confidence intervals (95% CI). Bold values have been used to mark the statistically significant results.
