The extracted data from the online survey were analyzed by STATA 15.0 software. We described data characteristics that covered frequency, percent, mean, and standard deviation. To compare differences between people having household income change due to the impact of COVID-19 and people who were not affected, we used t-test or Mann Whitney test for ordinal variables and Fisher-exact test or Chi-square test for nominal variables. Ordered logistic regression was employed to examine factors correlated with the impact of COVID-19 on respondents’ family income. A multivariable Tobit regression model was applied to identify factors associated with HRQOL score. A forward stepwise strategy was applied to obtain the final regression model with a threshold of the p-value is less than 0.2. A p-value of less than 0.05 was considered as statistical significance.
