Erectile Dysfunction Symptoms in Polydrug Dependents Seeking Treatment

We appreciate the kind comment made by the colleagues (Ayubi and Safiri, 2017) in observing that there were both misunderstandings in the abstract and in the text regarding the odds ratio (OR) values of marital status, which require an erratum in order to correct them. It should be mentioned that the logistic regression analysis used in this study followed standard procedure, first identifying the variables that were significant (p < 0.05) in the bivariate analysis, followed by a collinearity test which eliminated two variables, and finally the calculation of odds ratios. However, the table that was sent and published is incomplete, because it is missing a second part showing the data without the variables that were eliminated by the collinearity test.
