All datasets were tested for normality (KolmogorovSmirnov test) and homogeneity of variance (Levene’s test) to see if a oneway Analysis of Variance (ANOVA) could be used. All datasets failed at least one of these tests so a nonparametric equivalent, KruskalWallis test was used whereby there is a statistically significant difference (P =
