statistics software (SPSS 17.0 for Windows, SPSS Inc., USA), and an
HCA analysis was performed on the results. The within-groups linkage
method was applied, using cosine as a measure of dissimilarity for the
interval data.The rescaled distance cluster reveals the relative distance
between the combined clusters. Analysis of variance (ANOVA) was
performed by SPSS 17.0 software (SPSS Inc., USA).
