Figure 1.

Representation of the significant differences in contractility between small bowel smooth muscle strips from obese and non-obese patients. The values given represent a mean value of the ratio of maximum carbachol response for each strip to its weight, and the difference is significant. 4.39 ± 0.82 (n = 63) in the small bowel muscle strips from obese patients versus 3.87 ± 0.84 (n = 61) in the strips from control patients. (p = 0.029).
