In the original publication of the article, under the section “Statistical analysis”, the following sentence was published incorrectly as “The chi-square test and multivariate logistic regression analysis were used to calculate the correlations between categorical variables”. The correct sentence should read as follows, “The chi-square test was used to calculate the correlations between categorical variables”.
