Rate of change for cervical fluid impedance versus BBT. Rate of change for A cervical fluid impedance and B basal body temperature (BBT) over a 1-day window, 3-day window, 7-day window, and for the entire follicular phase. Bars expressed as average and standard deviation. Due to higher resolution in data measurements, cervical fluid impedance allows for significant differences in rate changes over time (*p < 0.05) for ovulation predication relative to BBT where no significant differences are detected
