- Does cord blood cortisol have a mediating effect on maternal prepregnancy body mass index and birth weight?
- Gyu Hong Shim
- Clin Exp Pediatr. 2023;66(1):24-25. Published online November 30, 2022

- Characteristics of z score systems for diagnosing coronary abnormalities in Kawasaki disease
- Gyeong-Hee Yoo
- Clin Exp Pediatr. 2022;65(9):448-449. Published online March 14, 2022
