If collinearity between variables was found, then the weaker variables were removed from the multivariate model.
No association between variables was found within the control group (not shown).
Possible interactions between independent variables were examined and no significant associations between independent variables were found.
No additional main effects or interactions between any variables were found (p values all > 0.32).
All the correlations between the variables were found to be statistically significant although the correlation rates were not high.
No interactions between independent variables were found.
Interactions between all variables were found to be non-significant.
However, no significant interaction between these variables were found.
Interaction terms were tested, however no interaction effects between independent variables were found.
On the one hand, significant positive correlations between the variables were found [ 39, 42, 65, 66] and, on the other hand, no significant results were observed [ 35].
