CYGB and bronchopulmonary dysplasia: Specifically, the odds ratios (ORs) for HCT (OR = 1.33, 95% confidence interval [CI]: −0.11 to 2.77), PLT (OR = 1.0, 95% CI: 0.98–1.03), and HGB (OR = 1.38, 95% CI: 0.42–4.49) did not reach statistical significance, suggesting these three parameters may not be independent influencing factors for BPD risk.
