t-tests were for two-tailed distributions with heteroscedastic variances conducted on the three pairwise comparisons of the three group samples. The same letter indicates that there was no detectable difference in the means of the groups (P>0.05).
See Materials and methods and Fig. 2 for an explanation of the structural treatment categories.
