# Registered: stratified random control (e3d)

The stratified AUROC and its CI are the registered R2′ statistic.

| random set | report AUROC | median P(Yes), injected | median P(Yes), null |
|---|---|---|---|
| random64_s1 | 0.837 | 2.28e-05 | 1.28e-05 |
| random64_s2 | 0.867 | 3.41e-08 | 1.50e-08 |
| random64_s3 | 0.819 | 1.65e-07 | 5.44e-08 |

* pooled AUROC (E3c statistic, for comparison): 0.650
* stratified AUROC (mean within sets): 0.841, 95% CI [0.791, 0.885] (paired bootstrap)
