Table 2.
Study sample characteristics by village (n = 39 individuals) and forest (n = 23 individuals), including sleep quotas and NPCRA analysis (village = 16 individuals, forest = 15 individuals).
| Village | Forest | Bayes factor or t-test | BF interpretation | |

| Time in bed (h) | 8.95 (1.51) | 8.93 (1.90) | 0.12 | Modest evidence for H0 |
| Total sleep time (h) | 5.84 (1.47) | 6.10 (1.41) | 0.44 | Weak evidence for H0 |

| Nap period duration (h) | 0.99 (1.01) | 1.05 (1.24) | 0.13 | Modest evidence for H0 |
| Wake after sleep onset (h) | 2.59 (1.09) | 2.44 (1.12) | 0.24 | Modest evidence for H0 |
| Sleep efficiency (%) | 65.08 (12.08) | 68.61 (9.58) | 6.69 | Modest evidence for H1 |
| Sleep fragmentation | 52.52 (19.66) | 47.07 (14.40) | 5.15 | Modest evidence for H1 |
| Non-parametric circadian rhythm analysis | ||||
| Relative amplitude | 0.87 (0.04) | 0.86 (0.11) | 0.34 | Weak evidence for H0 |
| Interdaily stability | 0.55 (0.10) | 0.55 (0.12) | 0.34 | Weak evidence for H0 |
| Intradaily variability | 0.09 (0.05) | 0.135 (0.05) | 2.55 | Weak evidence for H1 |
| L5 | 2096.56 (675.47) | 2372.20 (2149.57) | 0.37 | Weak evidence for H0 |
| M10 | 30,011.56 (7672.68) | 34,160.13 (14,315.79) | 0.50 | Weak evidence for H0 |
| M10 onset | 7:30 (0:38) | 7:24 (0:37) | t = 0.49, p = 0.63 | |
Data are presented as mean (standard deviation). Bayes factor is reported to assess differences in sleep quotas between the locations. Time value differences are assessed using t-tests.
