Fig 6. Number of 30 s segments containing contractile activity observed with and without delay in propagation.

(a) Number of segments with and without delay for each pairwise combinations of quadrants per subject. (b) Number of segments with delay for each pairwise combinations of quadrants across subjects. The solid horizontal line inside the box corresponds to median, the edges of the box are the 25th and 75th percentiles, the whiskers extensions are the most extreme data points, and “+” markers correspond to the outliers. Kruskal-Wallis analysis and Tukey’s least significant difference correction with 99% CI was applied.
