Table 3. Human rights restriction by country and year.

Data are shown as the mean (95% confidence interval) [standard deviation]. Simple main effects are adjusted by Bonferroni correction: P values are multiplied by the number of groups (i.e., 5 for countries and 3 for years). Interaction: P < 0.001, partial η2 = 0.022.
