Temperature-level and cycle temporal-structure metrics

Temperature-level and cycle temporal-structure metrics are associated with within-individual stability in humans (ICC > 0.5).

“values and cycle-to-cycle regularity of several metrics capturing temperature level and temporal structure of the cycle showed moderate to strong within-individual stability (ICC > 0.5).”
