Health & Medicine · Aug 26, 2026

GlucoFM transferred well across clinical cohorts and remained strong with extremely limited labels, outperforming competing methods in 11 of 12 cross-dataset tests and achieving the best average PR-AUC at every few-shot budget, while still requiring external validation due to one underperforming transfer and limited population diversity.

Health & Medicine · Aug 26, 2026

GlucoFM’s unlabeled CGM pre-training outperformed the strongest comparable baseline across 14 evaluations, raising average PR-AUC from 54.7 to 58.8 and leading most diabetes-risk, beta-cell dysfunction, and insulin-resistance tasks, while demonstrating promise for label-scarce clinical prediction without establishing deployment or causal validity.

Science, Technology & Innovation · Aug 26, 2026

GlucoFM improves CGM representation by combining slow glycemic-state and fast residual-event streams while preserving time-of-day and missingness, with dual-stream modeling outperforming single-stream alternatives on evaluated metabolic tasks.

Health & Medicine · Aug 26, 2026

GlucoFM’s learned CGM history improved individualized two-hour post-meal glucose trajectory forecasting beyond pre-meal glucose, meal composition, and participant characteristics, reducing MAE to 21.88 mg/dL versus 22.90 for the best baseline and 27.69 for a train-fold-mean baseline across 874 meal events from 34 participants.
