A new evaluation pipeline for non-invasive blood glucose level estimation using photoplethysmography (PPG) has revealed significant overestimation of model performance. When tested with stricter, participant-aware protocols, five representative PPG-based methods showed near-zero or negative R² values, comparable to a simple mean-prediction baseline. While over 90% of predictions fell within clinically acceptable zones on the Clarke Error Grid, this metric masked the models' failure to generalize, highlighting a critical disconnect between standard machine learning evaluation and real-world clinical utility.
