  1. Summary statistics of the full cohort, as well as for the consistently not highly variable and consistently highly variable user groups. We utilize a greater than 9 day median cycle length difference threshold to place users in each group—those in the consistently highly variable group represent the far end of a cycle variability spectrum.
