* p < 0.05, Model A is a univariate logistic regression model, using crude odds ratios (cORs) to explain the vaccine hesitancy in different risk perception groups. Region, age group, sex, marital status, education, and monthly household income per capita were adjusted in model B. In model C, we adjusted the rest covariates based on model B—history of chronic disease, history of COVID-19 vaccination, knowledge score on COVID-19, knowledge score on COVID-19 vaccination, as well as the other three aspects of risk perceptions. Model D only contained the significant covariates in Pearson χ2 test and the other three risk perceptions.
