To the Editor:
The authors regret that an important error in the result of Table 3, which is the 95% confidence interval (CI) of outpatient department (OPD) visit in home oxygen group, was confirmed in the following article: “Comparison of Follow-up Courses after Discharge from Neonatal Intensive Care Unit between Very Low Birth Weight Infants with and without Home Oxygen”, J Korean Med Sci 2017;32(8):1295–1303.
The corrected crude odds ratio (OR) and 95% CI of OPD visit in home oxygen group in Table 3 are: Crude OR (95% CI) 0.26 (0.16–0.44).
Thanks for good point of Martín Cañón, MD from Colombia about our article. That opinion has been a great help to us.
