Table 2.

Scores are expressed as Median and interquartile range (25th, 75th percentile). P-values are calculated by Mann-Whitney Rank Sum Test were P<0.05 indicates a statistically significant difference in the median values between the two groups and P>=0.05 indicates the difference in the median values between the two groups is not great enough to exclude the possibility that the difference is due to random sampling variability. Smooth muscle actin stain decreased at week 24
