Table 3.
Study cohort characteristics with respect to the two groups.
| Gray | Healthy Controls | Subjects with DT | Statistical Significance |
|---|---|---|---|
| n (total = 25) | 14 | 11 | N.A. |
| sessions (total = 37513) | 20556 | 16957 | n.s. (p = 0.98) |
| sessions per day (std) | 66.46 (42.54) | 55.14 (50.08) | n.s. (p = 0.49) |
| Demographics | |||
| Women # (%) | 6 (42.86%) | 4 (36.36%) | n.s. (p = 0.77) |
| Men # (%) | 8 (57.14%) | 7 (63.64%) | n.s.(p = 0.77) |
| Avg. Age (std) | 23.86 (4.44) | 23.55 (3.24) | n.s. (p = 1.00) |
| Subjects who completed Education Level H/U #/# | 10/4 | 9/2 | n.s. (p = 0.55) |
| Patient Health Questionnaire (PHQ-9) score | |||
| Avg. PHQ-9 (std) | 2.29 (1.73) | 10.64 (3.47) | sig. (p < 0.001) |
The two groups formed by subjects with/without depressive tendency were fairly matched in terms of demographics, with no statistically significant differences (p < 0.05) observed, except for the PHQ-9 score, which was the criterion for the subject categorization. Statistical significance was computed using the two-sided Mann-Whitney U test. N.A.: not applicable; sig.: significant; n.s.: non-significant.
