Classification of samples from the WR group
When the ensemble algorithm was applied to samples from the WR group, 22 (55%) samples were classified as adequate sleep (WR-ADEQUATE) and 18 (45%) samples were classified as insufficient sleep (WR-INSUFFICIENT).The PCA representation (Fig. Principal component analysis of the CON, SR, and WR samples. The color of samples from the WR group denotes how the ensemble algorithm classified each sample with light blue as WR-ADEQUATE (WR-ADD) and dark blue as WR-INSUFFICIENT (WR-SR). Ellipses level is 0.95.The classification of samples for individual WR participants are shown in Fig. Schematic representation of the classification of the samples of the participants from the WR group. The color of tik marks denotes how the ensemble algorithm classified each sample with black as WR-ADEQUATE, red as WR-INSUFFICIENT, and grey for the missing samples, the sex of the participant is symbolized by the shape of the character. For each participant, the first sample was collected at 1 h, the second at 13 h, and the third at 23 h after scheduled wake time.Exploratory comparison of characteristics from individuals with samples either classified as “insufficient” or “adequate” sleep after a weekend recovery. A participant was included in the WR-insufficient group if at least two of their three samples were classified as insufficient sleep, and the same logic was used to compose the WR-adequate group.
