Step 0: Unadjusted. Step 1: Adjusted for demographic variables. Step 2: Adjusted for demographic variables and objective risk of coronavirus disease 2019 (COVID-19) infection. Step 3: Adjusted for demographic variables and both perceived and objective risk of COVID-19 infection. Step 4: Adjusted for demographic variables, both perceived and objective risk of COVID-19 infection, and poor COVID-19 knowledge.
