      The authors regret that on p.192 of the above article, in the second paragraph of the “Statistical analysis” section, we omitted to write “hospital volume” as one of the covariates used for estimating propensity score. The sentence “We used age, sex, body mass index (BMI), Charlson Comorbidity Index score (CCI), cardiogenic arrest or not, cardiac arrest on admission, and post-admission therapy as covariates for estimating propensity score” should read “We used age, sex, body mass index (BMI), Charlson Comorbidity Index score (CCI), cardiogenic arrest or not, cardiac arrest on admission, post-admission therapy, and hospital volume as covariates for estimating propensity score”.
      There were also additional errors in the numbers in Table 1 (on p.193). The number of patients who received a red blood cell transfusion in the control group before propensity score matching, and the number of patients after propensity score matching in each volume hospital were incorrect. These errors occurred as a result of incorrect copying of data from the output of the statistical software to the table. The corrected table is shown below:
