Glomerular Hyperfiltration and Mortality in U.S. Adults, 14,309 Participants

A nationally representative cohort of 14,309 healthy adults from the National Health and Nutrition Examination Survey (NHANES). The dataset includes supplementary material for a study analyzing the link between glomerular hyperfiltration and all-cause mortality over a median follow-up of 123 months. The material was authored by figshare admin karger and last updated in May 2026.

Use Cases

• Modeling mortality risk based on estimated glomerular filtration rate (eGFR) and body surface area (BSA).
• Conducting propensity score matching analyses to assess the independent effect of glomerular hyperfiltration.
• Applying restricted cubic spline regression to explore non-linear relationships between kidney function and health outcomes.

Strengths

• Based on a nationally representative cohort of 14,309 healthy adults.
• Includes results from multiple analytical methods (Cox models, propensity score matching, restricted cubic splines).
• Provides specific hazard ratios and confidence intervals (e.g., fully adjusted HR: 1.86).

Limitations

• The primary data file is a 431.2 KB DOCX document, which is a small supplementary file rather than a raw dataset.
• Row count and column-level documentation for any underlying data are unknown.
• Description metadata is limited; actual data quality requires manual inspection after download.
