Nocturnal Heart Rate Variability in Women Discordant for Hormonal Contraceptive Use

What this work gives Aellic

Users of combined oral contraceptives are NOT signal-free: nocturnal HRV follows a real rhythm driven by the pill pack (higher during the pill-free interval). Aellic's strata sit at estimated ovulation, not at the pack boundary — so part of this is captured, but not all of it. A genuine pill-pack mode would be a development stage of its own; until then the position is: partially correct, never wrong, and documented.
