The indices presented are of different nature: the associations between nominal variables and continuous variables were measured with Eta index; the associations between ordinal variables and continuous variables were measured with Spearman index; the associations between continuous variables were measured with Pearson index; associations between nominal variables were measured with chi-square. Bold values are significant values (p < 0.05).
