Red Blood Cell Distribution Width to Albumin Ratio and Migraine Association

Rui Lu's research dataset explores the association between the red blood cell distribution width to albumin ratio (RAR) and migraine outcomes. It includes data from a clinical cohort at Zhongnan Hospital of Wuhan University from January 2024 to June 2025 and a population-based cohort from the NHANES database (1999–2004 cycles). The study employs multivariable logistic regression and subgroup analyses.

Use Cases

• Train predictive models for migraine risk based on biomarker ratios.
• Conduct epidemiological analysis of migraine associations using clinical and population survey data.
• Perform subgroup analysis to explore effect modification by age or BMI.
• Validate the RAR biomarker as a potential indicator for inflammatory processes in neurological conditions.

Strengths

• Data combines a clinical cohort with a large, public population survey (NHANES).
• Analysis includes multivariable logistic regression and tests for linear dose-response patterns.
• Results are reported with specific odds ratios and confidence intervals (e.g., OR=6.36, 95% CI: 2.04–19.82).

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The clinical cohort is from a single center, which may limit generalizability.
