  1. *A significant difference was not observed among any mean RSVs after bonferroni adjustment.
  2. **Mean RSV in CCAM was significantly lower than that in other weeks (p = 0.028).
  3. ***Mean RSV in CCPAEM was significantly higher than that in other weeks (p = 0.044).
  4. P values were calculated by Kruskal–Wallis test. CCAM, Cervical Cancer Awareness Month (January); CCPAEM, cervical cancer prevention awareness enhancement month (November).
