Research on the Characteristics of Infrared Radiation Spectra at Zigong Acupoint within Menstrual Cycle of Healthy Female

Table 3

(a) The wavelength number of infrared radiation intensity with statistical differences between EX-CA1 and control points

	No. of Wavelengths (The infrared radiation intensity of acupoints> that of control points)		No. of Wavelengths (The infrared radiation intensity of acupoints< that of control points		Total No. of Wavelengths with statistical differences between EX-CA1 and control points
	Left	Right	Left	Right	Left	Right
Before Menstruation	31	25	0	0	31	25
During Menstruation	33	1	0	0	33	1
After Menstruation	23	25	0	1	23	26

Note: Wavelengths range from 1.5μm to 18μm.

(b) Chi-square tests of the wavelengths number with statistical differences in infrared radiation intensity between EX-CA1 and control points

		No. of Wavelengths without statistical difference	No. of Wavelengths with statistical difference	-value	P-value
Before Menstruation	Left	35	31	1.272	=0.341
	Right	42	25
During Menstruation	Left	34	33	40.358	0.001
	Right	66	1
After Menstruation	Left	43	23	0.224	=0.769
	Right	41	26
