Post hoc mean comparisons showed significant differences (p < 0.05) among the 3 algorithms, with AlgoSmooth showing the highest NPV (AlgoSmooth: 76.6%; ACT80: 52.7%; and ACT40: 42.8%).Sleep Variable ConcordanceSleep variables calculated from PSG and estimated with the 3 actigraphy scoring algorithms for the 3 activity types are presented in Table 2.
