highly significantP = 0.045
In addition, pairwise analysis of similarity [ 25 ] suggested that there were highly significant differences between the Cn and Fe groups (global R = 0.139, P = 0.045), the Cn and FP groups (global R = 0.239, P = 0.004), the Cn and Po groups (global R = 0.253, P = 0.005), the Fe and FP groups (global R = 0.387, P = 0.003), the Fe and Po groups (global R = 0.436, P = 0.004), and the FP and Po groups (global R = 0.165, P = 0.05) ( Table 1 ).
