A lactate metabolism-related gene signature to diagnose osteoarthritis based on machine learning combined with experimental validation
Figure 6. Construction and validation of the diagnostic nomogram. (A) A nomogram was constructed to visualize the LR model. (B–D) ROC analysis shows the predictive ability of the nomogram in the training (B), validation-cartilage (C), and validation-synovial (D) cohorts. (E–G) Calibration analysis shows the predictive ability of the nomogram in the training (E), validation-cartilage (F), and validation-synovial (G) cohorts. (H–J) DCA analysis shows the predictive ability of the nomogram in the training (H), validation-cartilage (I), and validation-synovial (J) cohorts. Abbreviations: ROC, receiver operating characteristic; DCA, decision curve analysis; LR, logistic regression.
