Table 3. Results of 2-way ANOVA for total lying time and sleep time in the last and next 1 week.
| Last 1 week | Next 1 week | |
| Average of total lying time (hrs) | 8.4 ± 2.0 | 8.7 ± 1.7 |
| Average of sleep time (hrs) | 7.1 ± 1.3* | 7.1 ± 1.2* |
Main effect (last 1 week/next 1 week): F=0.820, p=0.367.
Main effect (total lying time/sleep time): F=28.164, p<0.001.
Interaction: F=0.871, p=0.353.
*Significant difference between total lying time and sleep time in each week (p<0.001).
