All variables were significantly different (P < 0.05) across educational levels (high school students, undergraduate students, graduate students) within the overall population and within given sex (male, female). Values under a given variable were shown in bold, 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 lockdown within a given educational level and sex was significant (*P < 0.05,**P < 0.01,***P < 0.001)
