^aDaily playtime is measured using a 1 to 6 scale. Table 1 provides further details (referenced as HR).

^bDescriptive statistics of daily playtime amount per depression severity levels: severe depression (n=50; mean 3.58, SD 1.75); moderately severe depression (n=140; mean 2.90, SD 1.49); moderate depression (n=254; mean 2.69, SD 1.32); mild depression (n=787; mean 2.60, SD 1.31); and minimal depression (n=663; mean 2.48, SD 1.35).

^cAll t tests were 2-tailed.
