Independent predictive potential of diagnostic FRLs. A Expression analysis of 6 diagnostic FRLs between BPD group and control group. Data was presented as mean ± SEM. Statistical comparison by unpaired t-test, * p < 0.05, ** p < 0.01. B Correlation analysis between 6 diagnostic FRLs. Red and blue indicated positive and negative correlations respectively. C ROC curve of LINC00348 (AUC = 0.796). D ROC curve of POT1-AS1 (AUC = 0.736). E ROC curve of LINC01103 (AUC = 0.706). F ROC curve of TTTY8 (AUC = 0.721). G ROC curve of LINC00691 (AUC = 0.697). H ROC curve of PACRG-AS1 (AUC = 0.71). ROC, receiver operating characteristic. AUC, area under the ROC curve
