A null result is one without the expected content, which does not support the hypothesis (Wikipedia). In cancer AI the published record is skewed towards wins, so frozen-foundation-model results that fail to beat a baseline, panels that wash out a gain or pretraining at scale that adds nothing are worth recording as findings, with the seeds, versions and checksums that let them be rerun.","asOf":"2026-09-24","wikipedia":"https://en.wikipedia.org/wiki/Reproducibility","links":[{"label":"Wikipedia: null result","url":"https://en.wikipedia.org/wiki/Null_result"},{"label":"Wikipedia","url":"https://en.wikipedia.org/wiki/Reproducibility"}],"tags":["cansim-terms"],"related":["cancer-ai-vocabulary"],"cancers":[],"sections":[],"technologies":[],"targets":[],"drugs":[],"companies":[],"institutions":[],"pathways":[],"terms":["provenance-fields","pre-registered-experiment","model-card","leaderboard-benchmark"],"trials":[],"people":[],"bottlenecks":[],"keyPapers":[],"journals":[],"dependsOn":[],"notes":["Listed in the CanSim terms map 1.0.0 (docs/onco/terms.json, generated 2026-09-24), CC BY 4.0, attribution: CanSim project, an open, public-data-first cancer foundation-model programme; CanSim page path /terms/reproducibility."],"provenance":{"editedBy":"OnCo CanSim terms wave (Wikipedia summaries, standards and project pages, GDC and FDA pages, Europe PMC)","editedOn":"2026-09-24","note":"CanSim terms map 1.0.0 (docs/onco/terms.json, generated 2026-09-24), CC BY 4.0, attribution: CanSim project, an open, public-data-first cancer foundation-model programme"},"category":"Methods and models"},"route":"/terms/reproducibility/","neighbours":{"term":[{"id":"leaderboard-benchmark","kind":"term","name":"Benchmarks, leaderboards and contamination","route":"/terms/leaderboard-benchmark/"},{"id":"cancer-ai-vocabulary","kind":"term","name":"Cancer AI vocabulary (CanSim terms map)","route":"/terms/cancer-ai-vocabulary/"},{"id":"citation-cff","kind":"term","name":"CITATION.cff (Citation File Format)","route":"/terms/citation-cff/"},{"id":"model-card","kind":"term","name":"Model cards and datasheets for datasets","route":"/terms/model-card/"},{"id":"pre-registered-experiment","kind":"term","name":"Pre-registered experiment","route":"/terms/pre-registered-experiment/"},{"id":"provenance-fields","kind":"term","name":"Provenance fields for research data","route":"/terms/provenance-fields/"},{"id":"zenodo-doi","kind":"term","name":"Zenodo DOIs for data and code","route":"/terms/zenodo-doi/"}]}}
