Due to the carelessness of the authors, in the article, “Comparison of C50 for Propofol-remifentanil Target-controlled Infusion and Bispectral Index at Loss of Consciousness and Response to Painful Stimulus in Elderly and Young Patients”, which appeared in the pages 1994-1999, Issue 15, Vol 128 of Chinese Medical Journal,[1] the word “Weight, kg” in Table 1 under the first column is incorrectly written instead of “Age, years”.Additionally, the numbers “19/33” and “25/27” in Table 1 under the second and third columns are incorrectly written instead it should be written as “19/21” and “23/17” respectively.These have now been corrected and reposted online.
