Mediation Analysis Results for Cognitive Reserve in UK Biobank

Laura Bravo-Merodio published mediation analysis results on figshare in June 2026. The 5.5 KB XLS file contains results from a study modeling interactions between education, neurobiological features, and cognitive outcomes in the UK Biobank cohort. The analysis used machine learning and mediation analysis to test a hypothesis about the noradrenergic system's role in cognitive reserve.

Use Cases

• Validate mediation models of cognitive reserve based on neurobiological connectivity features.
• Investigate the role of right fronto-parietal network connectivity as a mediator between education and cognition.
• Replicate machine learning analyses on the interaction between genetic variants in noradrenergic signalling and cognitive outcomes.

Strengths

• Results are derived from the large-scale UK Biobank cohort.
• Analysis integrates multiple data types: genetic variants, structural/functional connectivity, and cognitive test scores.
• Dataset is openly licensed under CC-BY-4.0.

Limitations

• The dataset is very small at 5.5 KB, suggesting it contains summary results rather than raw or processed data.
• Row count and column-level documentation are absent; data structure must be inferred after download.
• Description metadata is limited; actual data quality requires manual inspection after download.
