*Values under a given variable were shown in bold, if the difference across educational levels (high school students, undergraduate students, graduate students) within the overall population (total) or within a given sex (male, female) was significant; shown in italic, if the difference between sexes within a given educational level was significant; and marked by asterisks, if the difference during or after COVID-19 within a given educational level and sex (relative to ‘before lockdown’) was significant (*P < 0.05, **P < 0.01, ***P < 0.001). P - values were based on χ2 tests.
