Harvard Dataverse hosts replication data from a prospective diagnostic accuracy study authored by Suneet Sood. The dataset contains paired readings from a test device (Vivaray Hb Pro) and a reference device (Coulter blood cell counter). It was last updated on April 27, 2026.
Use Cases
- Assessing device agreement based on the difference between test and reference readings.
- Conducting Bland-Altman analysis based on the mean and difference values for each paired measurement.
- Validating noninvasive hemoglobin measurement technology based on the comparison with a calibrated laboratory standard.
Strengths
- Data is structured for direct comparison, containing test readings, reference readings, their mean, and their difference.
- The study is a prospective diagnostic accuracy study, suggesting a controlled methodological design.
- The dataset was last updated on April 27, 2026, indicating recent maintenance.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment for large-scale modeling.
- Description metadata is limited; actual data quality requires manual inspection after download.
