/In our study, we had examined the tissues collected from the native bladder tissue and compared against its own grafted tissue. There were three baboons in each of the three study groups, and 2 tissue samples from each animal, either grafted (for E group) or regenerated (for CS-POCO and CS-SIS) and native tissue samples, resulting in a total of 18 tissue samples as shown in Figure 1. The box plot was created to visualize the variation in abundances of mass spectrometric signals across different samples and conditions. As shown in the figure, the IR for all 18 samples was similar and consistent across all samples indicating a uniform distribution of the data and suggested a tightly grouped result set. Since the median of the data was similar across all samples, there were minimal number of outliers and minimal variations variables or shifts amongst the samples.
