The means with the same superscript letter are not statistically different (p > 0.05). The mean MTBS values for each group are listed in decreasing order, the superscript letters (“a “ to “f“) categorized according to their statistical significance. The statistically significant letters are marked on the mean MPa in order from the highest value. That is, “a” represents the most statistically significant MTBS value, and “f” represents least the statistically significant MTBS value.
