Values in same row with different subscript ‘a’ and ‘b’ are significantly different at p<0.05 in the two-sided test of equality for column proportions.
*Comparisons are currently based on bivariate analysis alone and do not control for potential confounders. Hence, any significant differences between ‘aware’ and ‘unaware’ groups must be interpreted with caution.
