- Multimarker integration improves reconstruction:
Combining fast- and slow-kinetics biomarkers (BAC, BrAC, EtG, EtS, UAC) provides more complete temporal information than traditional single-marker approaches. - Mechanistic digital twin enables personalization:
The model incorporates physiological processes (e.g., liver metabolism, fluid distribution, gastric emptying) and individual characteristics to simulate alcohol kinetics in specific individuals. - Validated but limited real-world testing:
The framework was trained on multiple datasets and validated against one independent study, with additional evaluation in two individuals, demonstrating alignment with observed biomarker profiles. - Improves differentiation of similar drinking scenarios:
Simulations showed that multimarker analysis can distinguish between intake patterns that appear similar when assessed using BAC alone. - Designed for plausibility assessment, not definitive reconstruction:
The model is intended to evaluate whether a reported drinking scenario is consistent with observed data, with uncertainty in inputs reflected in broader prediction ranges.
