Data for Choline Biomarker is a master table from a double-blind randomized crossover controlled feeding study. The dataset contains choline and betaine concentrations in plasma, which were used to discriminate levels of dietary choline intake in healthy adults. The dataset was authored by Trujillo-Gonzalez, Isis and last updated on 2026-04 27.
Use Cases
- Modeling the relationship between dietary choline intake and plasma biomarker levels based on the controlled feeding study design.
- Developing diagnostic thresholds for choline deficiency or sufficiency based on plasma choline and betaine concentrations.
- Validating dietary assessment methods by comparing reported intake against measured plasma biomarker levels.
Strengths
- Data originates from a double-blind randomized crossover controlled feeding study, a rigorous experimental design.
- The dataset focuses on specific biomarkers (choline and betaine) in plasma for a targeted analysis.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment for statistical modeling.
