# # Study Overview
A randomized controlled trial enrolled caregiver-child dyads in a 10-week comparison of a multicomponent garden-based intervention (SHA) and an education-only control (MSP).
# # Key Findings
- Molecular sensitivity: Fecal multi-omics detected intervention-associated differences in metabolites, lipids, and bile acids that traditional clinical indicators failed to capture.
- Age effect: Children showed more apparent molecular variation than caregivers (adults) in response to the garden-based intervention.
- Network links: Network analysis identified associations between selected molecular features and cardiovascular-related indicators, including blood pressure, body fat, skin carotenoids, and Healthy Eating Index scores.
# # Framework Role
The BIOCARD framework is proposed as a complementary exploratory tool to traditional outcome measures for evaluating nutritional cardiovascular interventions, not as a replacement. Its clinical validity and reproducibility remain to be established.
# # Limitations
- Sample size not reported in the abstract; may limit statistical power for multi-omics analyses.
- Short 10-week intervention duration limits conclusions about long-term cardiovascular outcomes.
- Fecal multi-omics reflect proximal gut environment; causal links to systemic cardiovascular health are unestablished.
- Framework described as exploratory; clinical validity and reproducibility not yet established.
