Reported quantities
| Role | Count | Unit | Scope | Basis | Evidence |
|---|---|---|---|---|---|
| Primary | 53,188 | embedding_vectors | Rows across six model-specific CSV files Two BRSET files contain 16,266 rows each and four mBRSET files contain 5,164 rows each. | derived_from_reported_components | physionet.org/content |
| Additional | 21,430 | images | Distinct parent images represented by at least one embedding This is 16,266 BRSET plus 5,164 mBRSET images; it is not a new image cohort. | derived_from_reported_components | physionet.org/content |
Counts retain their source-reported units. Additional rows can describe components, paired items, or derivative copies and are not automatically added to the primary quantity.
