Table 2. Binary logistic regression of attitude and change in behavior toward single-use plastic bags with sociodemographic variables.
*Represents p-value < 0.05, which is considered statistically significant; unadjusted OR with 95% confidence interval (CI).
The significant factors that satisfied p < 0.05 were considered for binary logistic regression analysis, which is represented with adjusted odds ratio (AOR) with 95% CI, and its corresponding p-value at <0.05 is considered statistically significant.
