Evaluation of retrieval performance across the ROCO and MIMIC-CXR medical imaging datasets, specifically measuring correlation using Spearman's rank coefficient.

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.

| Scope | Recorded value |
| --- | --- |
| Task | Spearman rank correlation with retrieval |
| Dataset (including any stated split) | Medical Domain ROCO, MIMIC-CXR |
| Metric | Spearman Rho |
| Unit | SCALAR |
| Direction | Higher is better |
| Results loaded | 9 of 9 |
| Coverage | All results currently returned for this benchmark |

Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol.

## Metrics

- [Spearman Rho](<https://www.sota2.com/research/sota/spearman-rank-correlation-retrieval-on-roco-and-mimic-cxr.md?metric=Spearman%20Rho>): Higher is better; unit: SCALAR.
