Unauthorized reproduction of this article is prohibited. ACCEPTED We thank you for the response to our paper. We agree with the author that our study has some limitations. There has been a debate about what statistical methods to use in the analysis of the response to transforaminal epidural steroid injection (TESI) . The primary outcomes used are VAS for leg pain and disability, both of which are continuous variables. The debate has been about whether to keep the continuous primary outcomes or to dichotomize them into response rate. A continuous variable may be preferred to a dichotomized variable due to the fact that all available information is used. Pinto et al used this method but was criticized for it because of its shortcoming . Namely, the subjects with negative response to TESI will have a too great impact on the mean outcome.
