We appreciate the interest of Drs. Ayubi and Safiri in our study and their insightful comments [1]. We will be able to investigate the validity of our constructed model once the number of events increases in the future. We believe that their comments will help to improve the quality of our future studies greatly. As mentioned in their letter, multivariate results can be biased because of multicollinearity if this phenomenon is not checked during the univariate phase. The multicollinearity among the variables was investigated before their inclusion in the multivariate model, although we did not mention this point in our manuscript [2].
