  1. Note: Percentage of supportiveness refers to the proportion of respondents who had a supportive attitude to the NPI strategy to control the spread of COVID-19. ARR, absolute risk reduction. NNT, number needed to treat. P (two-tailed) was based on the z-ratio test. †case was adjusted by matching of the propensity score based on age, sex, degree course, primary degree, depression score, anxiety score, or exposure history
