  1. Repeated-measures analysis of variance (ANOVA) & Multiple comparison between groups through Post Hoc test: Bonferroni-corrected. Letters A-E comparatively represent the descending order of results reflecting importance among means at the same time. p-value > 0.05 is insignificant; *p-value < 0.05 is significant; **p-value < 0.001 is highly significant
