We thank Agrawal et al. [1] for their interest in our recent retrospective study investigating postoperative complications after selective dorsal rhizotomy (SDR) [7]. In the present letter to the editor, Agrawal et al. [1] refer to the already discussed limitations of the study. We would like to summarize again the key arguments we discussed, as follows:
1.
2.
Cutoff values of thrombocytes and hemoglobin were determined using a receiver operating characteristic curve, which was mentioned in the section material and methods [7]. We do agree with the authors that the results regarding thrombocytopenia as a risk factor for SSI have to be interpreted with caution due to the low number of events. We discussed the limitation of our findings by the low number of events preventing a multivariate analysis.
