This chapter summarizes how analytic samples overlap across genotyping and polygenic scores, neuroimaging, DNA methylation, RNA sequencing, miRNA, and whole-genome sequencing resources in BHRC.

All displayed values are aggregate counts or plots. Participant identifiers are used only inside the controlled local analysis workflow to calculate overlap and are not included in the rendered website.

Cross-modality overview

The heatmap below reports overlap between resources at any observed wave, before modality-specific quality control. Each cell shows the shared raw count and the percentage of the row dataset represented by that overlap. The diagonal is therefore 100%. The two interim miRNA sources are combined for this overview and remain separated in the detailed tables below.

Pairwise overlap by index dataset

Percentages in the detailed tables use the named section dataset as the denominator. “Overall” means availability at any observed wave.
