Figure 2 Abdominal withdrawal reflex pressure threshold measured in response to colorectal distension. Data are presented as mean ± SD, ^bP < 0.01 vs control; ^dP < 0.01 vs irritable bowel syndrome; ^fP < 0.01 vs TongXieYaoFang. Statistical comparisons were performed using One-way ANOVA followed by Dunnett’s test using GraphPad Prism 5.0. (n = 9 or 10). IBS: Irritable bowel syndrome; SGD: Shugan decoction; TXYF: TongXieYaoFang.
