Values are given as a percentage or mean ± SD. SD, standard deviation. Values under a given variable were shown in bold, if the difference across educational levels (high school students, undergraduate students, and graduate students) within the overall population (total) or within a given sex (male and female) was significant (p < 0.05); shown in italic, if the difference between sexes within a given educational level was significant (p < 0.05); and marked by asterisks, if the difference before and after COVID-19 within a given educational level and sex was significant
