  • AOR was derived from multivariable logistic regression model mutually adjusted for all other sociodemographic factors.

  • COR was derived from bivariate logistic regression model.

  • Bolded values are two-sided p values<0.05.

  • *Overall p value.

  • †Of all participants, 21.5% did not provide information on their average monthly household income. They have been categorised as ‘unknown income’ and included for analysis.
