fWe also tested 7-variable models including both parent-reported and teacher-reported self-concept and self-control as predictor variables of mental health resilience residuals, in addition to the 5-variable models presented.
Models including all significant neighbourhood environmental characteristics, destination variables and interaction effects from the single-destination-variable models (presented above) could be estimated given that the intercorrelations between the variables were lower than 0.50, indicating no multicollinearity problems.
Considering the interrelationships among our variables, the models presented are the most appropriate.
None of the other variables included in the models presented statistically significant associations with risk.
The theory of the plastic shear variable engagement model presented a good basis for their shear design and a good relationship to the experimental results; the ratio of shear strengths obtained from experiment and theory was found to be 0.92, with a coefficient of variation of 0.12.
It is worth noting that use of antenatal care (ANC) during the pregnancy was not included as an independent variable in the reduced form models presented.
Hence, final models presented include variables based on the known outcome-related risk factors, possible confounders, or variables that differed between patients with and without OSA, regardless of the presence of collinearity.
For simplicity, these variables were omitted from the models presented in the article.
Higher levels of self-efficacy at baseline were strongly predictive of screening uptake and the effects of demographic variables remained consistent with the models presented previously.
These variables were excluded from the models presented here, because they correlated strongly with the study persons' educational level, but had no impact on the estimates for the other variables.
