  1. *Odds ratios were calculated based on 10 years interval.
  2. AOR = Adjusted odds ratio; multivariable logistic regression models were formulated to determine the likelihood of participation in the screening program for each biennial period spanning from 2011 to 2018. The data pertaining to evacuation statuses were procured from 2011, whereas the other explanatory variables used in the models were sourced from 2009 to 2010.
