Biomarker evaluation - c-statistic (AUC) and alternatives

This is a complaint. I used decision curve analysis in my paper and wrote the following expression. A collaborator told me that I was treating clinicians like idiots. I might lack sufficient knowledge, but I don’t understand why saying this is considered treating clinicians like idiots. Is this sentence offensive? > However, the C statistics are challenging for clinicians to interpret. The incremental predictive value of triglyceride levels requires interpretable metrics for quantification.
