Overlap statistics
Set-list statistics require a defined background universe. VennScope reports one-sided hypergeometric enrichment, two-sided Fisher exact p-values, odds ratios, 95% confidence intervals and Benjamini–Hochberg adjusted q-values. A t-test is not appropriate for identifier-only lists because no continuous replicate measurements are supplied.
| Pair | Shared | Universe | Odds ratio | 95% CI | Fisher p | Hypergeom p | BH q |

* Odds-ratio estimate uses a 0.5 Haldane–Anscombe correction when any 2×2 table cell is zero. Statistical tests use inclusive pairwise membership and require a valid universe containing all analysed identifiers.

Diagram geometry is schematic. Numerical set and intersection values are exact for the parsed inputs. Font choices use only fonts installed on the user's device; no remote fonts are requested.
Figure information
Exact vs inclusive
Exact A ∩ B excludes identifiers also present in other sets. Inclusive A ∩ B includes them.
Venn vs UpSet
Venn is recommended for two or three sets. For larger comparisons, UpSet is usually clearer and does not force complex circle geometry.
Reproducible export
For verified exports, the final file is hashed locally. Only the hash and export metadata are registered; raw identifiers remain on your device.
