We are working on a predictive model using Lasso to evaluate the validation cohort using publicly available data.

1. ROC-AUC 0.800 (95%CI 0.551-1.000)

2. ROC-AUC 0.750 (95%CI 0.350-1.000)

3. ROC-AUC 0.575 (95%CI 0.317-1.000)

I am wondering how to describe the evaluation of (2): please let me know if I can describe (1) and (2) as being well predicted statistically. Since the lower 95% CI limit is 0.35, despite the high ROC-AUC of 0.75, shouldn't we describe the evaluation of the model positively? thank you so much for your support.
