Chang Won Choi, Beyong Il Kim, Ee-Kyung Kim, Eun Song Song, and Jung-Ju Lee. Incidence of Bronchopulmonary Dysplasia in Korea. J Korean Med Sci 2012; 27: 914-21.
In the figure 3, designation of severity of bronchopulmonary dysplasia (BPD) was misprinted. Open bars (white) represent severe BPD, not mild BPD. Closed bars (Black) represent mild BPD, not severe BPD. Gray bars in the middle represent moderate BPD without change.
Corrected Fig. 3
