Note 1: When chi-square tests were performed to see the proportional differences between the outcome variables and explanatory variables, they were significant except- education and aware; education and treated, age category and controlled

Note 2: The relatively high non-response rate among the study respondents (any males and females aged 18 years or more) was random in nature and did not distort the outcome variable estimates
