Fig. 2

Physiological parameters of the regular group in the different phases of the menstrual cycle. Changes in BBT (A), HR (B), SDNN (C) and the LF/HF ratio (D) during the menstrual cycle of regular menstruators are depicted. The horizontal line represents the medians, boxes represent the values between 25–75%, and lines represent the values between 5–95%. BBT: basal body temperature; HR: heart rate; LF/HF: low frequency /high frequency ratio; SDNN: standard deviation of normal-to-normal intervals
