CRD test results after EA. CRD4: responses to colorectal distension in 4 groups after first time EA (F3,16=3.216, 𝑃=0.051); CRD5: responses to colorectal distension in 4 groups after third-time EA (F3,16=5.853, 𝑃=0.007, in Z+C versus S+A, Z+C versus S+C); CRD6: responses to colorectal distension in 4 groups after fifth-time EA (F3,16=10.541, 𝑃<0.001, in Z+C versus S+C, Z+C versus S+A, and Z+C versus Z+A). Acupoints: schematic representation of the ST36 and ST37.
