Effect of Siguan Acupuncture on Gastrointestinal Motility: A Randomized, Sham-Controlled, Crossover Trial

Table 2

Change in exponential weighted score at four different time points.

Time point	Group	Exponential weighted score	𝑡 value	P value	95% confidence interval
6 h	RA group	12.8 ± 10.9	0.458	0.653	(7.6, 18.0)
	SA group	14.1 ± 9.80			(9.4, 18.8)
12 h	RA group	43.5 ± 16.2	1.112	0.282	(35.8, 51.2)
	SA group	49.6 ± 22.8			(38.7, 60.4)
24 h	RA group	66.9 ± 20.0	2.220	0.041*	(57.5, 76.4)
	SA group	76.1 ± 17.1			(68.0, 84.3)
48 h	RA group	92.1 ± 13.5	1.258	0.226	(85.7, 98.5)
	SA group	96.1 ± 7.70			(92.4, 99.7)

The results show altered values of the weighted score for radio-markers movement in the RA and SA groups at four different time points compared with time 0. The results are expressed as the mean ± standard deviation.
*Represents a significant difference between the two groups with P < 0.05 as assessed via Student’s t-test.
