The authors would like to note an error in the Data Analysis section, Figure 1 heading and Table 3 heading. Each, incorrectly, refer to ‘multivariate regression model’, ‘regression model’ and ‘multivariate regression analysis’. The correct terms are: ‘regression models’ and ‘multiple regression’. The procedure involved two univariate regression equations, rather than a single multivariate model. This error has no implications for the analyses or the reported results.
