Pairwise comparisons and Cohen d values for the association between the change in daily playtime^a and anxiety severity^b.

^aChange in daily playtime is measured using a 1 to 5 scale. Table 1 provides further details (referenced as CH).

^bDescriptive statistics of change in daily playtime per anxiety severity levels: severe anxiety (n=36; mean 4.36, SD 0.72); moderate anxiety (n=159; mean 3.77, SD 0.92); mild anxiety (n=723; mean 3.73, SD 0.81); and minimal anxiety (n=976; mean 3.66; SD 0.84).

^cAll t tests were 2-tailed.
