Supplementary Datasheet 4: Four-Way Decomposition Results with WBC Adjustment

A 19.6 KB supplementary datasheet from a 2026 study on epigenetic aging and frailty. The file contains four-way decomposition results with leukocyte (WBC) adjustment, derived from analyses of the NHANES and HRS surveys. It was authored by May A. Beydoun and shared under a CC-BY-4.0 license.

Use Cases

• Replicate statistical mediation/moderation analyses based on the four-way decomposition method described.
• Assess the role of leukocyte count as a confounder in associations between epigenetic markers and health outcomes.
• Compare effect estimates from two major U.S. health surveys, NHANES and HRS, as referenced in the description.

Strengths

• File size is precisely 19.6 KB, indicating a focused, supplementary result set.
• Data is associated with peer-reviewed research on epigenetic aging markers, providing academic context.
• License is clearly defined as CC-BY-4.0, permitting open reuse with attribution.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Description metadata is limited; actual data quality requires manual inspection after download.
