摘要
Dear Sir,Since the present study is mainly an observational study,though prospective,we did not use any particular treatment methods for all traumatic brain injury(TBI)patients.The main purpose of the research is to investigate the relationship between calcitonin gene-related peptide(CGRP)and clinical outcomes.Thus we did not describe the details of surgery and treatment procedures for all patients.All patients underwent a regular treatment routine.We had included a sentence of“All patients were treated according to the locally agreed management protocols for head injury.”However,it was asked to be deleted during revision.
