Fig. 5From: A predictive model for preterm infants with bronchopulmonary dysplasia based on ferroptosis-related lncRNAsDiagnostic FRLs in preterm infants with BPD. A-B 6 diagnostic FRLs were determined using the random forest classifier Gini coefficients algorithm. C 8 diagnostic FRLs were obtained using LASSO regression. D Optimal λ selection in the LASSO regression. E Intersection results of random forest and LASSO regression, with a total of 6 diagnostic FRLs finally screened out.
