Comparison of fragmentation and restriction nights
During baseline nights, participants underwent full somnography and during the intervention-nights, only necessary sensors were applied, so the disturbance of sensors might have been lessSDNN was significant lower during WASO in R (65.25 ms ± 26.73) than during WASO in F (81.94 ms ± 33.12) with a weak effect size of r = 0.28 (
