Interpretation: The quote says menstrual discharge ceases in most women about the fortieth year, lasts to the fiftieth in some, that women of that age have borne children, and that beyond that age there is no case on record. Qwen's partial verdict was that births to women past fifty are too sparse to settle the last clause. That clause is not measurable in the public files checked before registration: NHANES top-codes age at last live birth at '45 or older', Eurostat's open age is Y_GE50, and the Human Fertility Database zip redirects to a login. The test therefore scores the menstrual clause and the existence of births at 48 and 49, and it says so. It does not claim to have tested the absence of births after 50. The sample for menopause is United States residents interviewed in 2017-2018 who gave menopause as the reason periods had stopped. https://w3id.org/delphi/resource/assessment/aristotle-ha07-14--claim-test--pr-109 http://www.w3.org/2000/01/rdf-schema#label Claim test of aristotle-ha07-14 (pr-109): refutes, confidence 0.75 https://w3id.org/delphi/resource/assessment/aristotle-ha07-14--claim-test--pr-109 http://www.w3.org/2000/01/rdf-schema#seeAlso https://github.com/fractastical/delphisci/blob/bf2af6ee0a84e23ffa6414ad7a0a50a8c276506e/test-data/claim-tests/aristotle-biology/aristotle-ha07-14/pr-109/result.json https://w3id.org/delphi/resource/assessment/aristotle-ha07-14--claim-test--pr-109 http://www.w3.org/ns/prov#wasAttributedTo https://w3id.org/delphi/resource/agent/delphisci-claim-tester-grok-4-7 https://w3id.org/delphi/resource/assessment/aristotle-ha07-14--claim-test--pr-109 https://w3id.org/delphi/ontology/admissibleDatasets A public health-interview file that separates menopause from hysterectomy and records age at the last menstrual period in single years, plus a civil-registration series of live births by single year of the mother's age through 49.

Codebook labels, including RHD043 code 7 and the RHQ060 and RHD190 special codes, were read from the NHANES HTML documentation, which also prints frequencies.

The claim is refuted when both the weighted and the unweighted medians of exact age at natural menopause are at or below 35 or at or above 45, so that cessation is not 'about forty' for most women in this sample.

The universal negative 'no birth after 50' is not assigned a verdict. No assessor score is used. https://w3id.org/delphi/resource/assessment/aristotle-ha07-14--claim-test--pr-109 https://w3id.org/delphi/ontology/passCriterion Pre-registered. Menopause: NHANES 2017-2018 RHQ_J, women with RHD043 equal to 7 (Menopause/Change of life), exact RHQ060 ages from 20 through 59 inclusive. Codes 19, 60, 777, and 999 are excluded from the median. Weighted median uses DEMO_J WTINT2YR by the same cumulative-weight rule as the menarche test (smallest age at which cumulative positive weight reaches half the total). Unweighted median uses equal weights. Near means both medians are in [38, 42]. Far means a median is less than or equal to 35 or greater than or equal to 45. The tail condition holds if at least 10 included women have an exact age in [48, 52] and that count is at most half of the included women. Births: Eurostat demo_fagec, ages Y48 and Y49 only, summing the marital-status total if a total category is present and otherwise summing the non-total marital categories, and summing only geographic codes of length 2 (aggregates such as EU, EA, EEA, and codes containing an underscore are excluded). Supports only if both menopause medians are near, the tail condition holds, at least 100 included menopause ages remain, and the summed Y48 plus Y49 births are at least 1. Refutes if both medians are far and at least 100 included ages remain. The far rule wins over the support rule. Mixed if the medians are gray or disagree, or the medians are near but the tail or the Eurostat birth count fails the support rule, or Eurostat cannot be fetched when the medians are near. Inconclusive with reason 'data-unavailable' if the NHANES files or WTINT2YR cannot be used. Inconclusive with reason 'underpowered' if fewer than 100 included menopause ages remain. Inconclusive with reason 'other' if code 60 or code 19 exceeds 5 percent of RHQ060 values among RHD043=7. Y_GE50 is downloaded and reported and is not used in the verdict, because that bin includes age 50 and cannot show a birth after 50. NHANES RHD190 is not used, because the public code 45 means '45 years or older' and cannot separate age 50 from later ages. Confidence: 0.75 if refutes, 0.50 if supports, 0.55 if mixed. https://w3id.org/delphi/resource/assessment/aristotle-ha07-14--claim-test--pr-109 https://w3id.org/delphi/ontology/preregistered false https://w3id.org/delphi/resource/claim/aristotle-ha07-14 https://w3id.org/delphi/ontology/hasAssessment https://w3id.org/delphi/resource/assessment/aristotle-ha07-14--claim-test--pr-109 https://w3id.org/delphi/resource/evidence/aristotle-ha07-14--claim-test--pr-109--dataset-1 http://purl.org/dc/terms/description age at last menstrual period among women who gave menopause as the reason periods had stopped https://w3id.org/delphi/resource/evidence/aristotle-ha07-14--claim-test--pr-109--dataset-1 http://purl.org/dc/terms/license U.S. government public-use file (National Center for Health Statistics) https://w3id.org/delphi/resource/evidence/aristotle-ha07-14--claim-test--pr-109--dataset-1 http://www.w3.org/1999/02/22-rdf-syntax-ns#type https://w3id.org/delphi/ontology/EvidenceItem https://w3id.org/delphi/resource/evidence/aristotle-ha07-14--claim-test--pr-109--dataset-1 http://www.w3.org/2000/01/rdf-schema#label Dataset: NHANES 2017-2018 Reproductive Health (RHQ_J) https://w3id.org/delphi/resource/evidence/aristotle-ha07-14--claim-test--pr-109--dataset-1 http://www.w3.org/ns/prov#atLocation https://wwwn.cdc.gov/Nchs/Data/Nhanes/Public/2017/DataFiles/RHQ_J.xpt https://w3id.org/delphi/resource/evidence/aristotle-ha07-14--claim-test--pr-109--dataset-1 http://www.w3.org/ns/prov#wasDerivedFrom https://wwwn.cdc.gov/Nchs/Data/Nhanes/Public/2017/DataFiles/RHQ_J.htm https://w3id.org/delphi/resource/evidence/aristotle-ha07-14--claim-test--pr-109--dataset-1 https://w3id.org/delphi/ontology/hasChecksum sha256:c919896216154ea207470dd84e428f5fdd65ced39735148c78fb6032e0b77a7b https://w3id.org/delphi/resource/evidence/aristotle-ha07-14--claim-test--pr-109--dataset-2 http://purl.org/dc/terms/description interview weight WTINT2YR https://w3id.org/delphi/resource/evidence/aristotle-ha07-14--claim-test--pr-109--dataset-2 http://purl.org/dc/terms/license U.S. government public-use file (National Center for Health Statistics) https://w3id.org/delphi/resource/evidence/aristotle-ha07-14--claim-test--pr-109--dataset-2 http://www.w3.org/1999/02/22-rdf-syntax-ns#type https://w3id.org/delphi/ontology/EvidenceItem https://w3id.org/delphi/resource/evidence/aristotle-ha07-14--claim-test--pr-109--dataset-2 http://www.w3.org/2000/01/rdf-schema#label Dataset: NHANES 2017-2018 Demographics (DEMO_J) https://w3id.org/delphi/resource/evidence/aristotle-ha07-14--claim-test--pr-109--dataset-2 http://www.w3.org/ns/prov#atLocation https://wwwn.cdc.gov/Nchs/Data/Nhanes/Public/2017/DataFiles/DEMO_J.xpt https://w3id.org/delphi/resource/evidence/aristotle-ha07-14--claim-test--pr-109--dataset-2 http://www.w3.org/ns/prov#wasDerivedFrom https://wwwn.cdc.gov/Nchs/Data/Nhanes/Public/2017/DataFiles/DEMO_J.htm https://w3id.org/delphi/resource/evidence/aristotle-ha07-14--claim-test--pr-109--dataset-2 https://w3id.org/delphi/ontology/hasChecksum sha256:c0b46e0345ea19404928656277c8b0d10b0cca348a9b2fe4fc3c67e8b7ee73ec https://w3id.org/delphi/resource/evidence/aristotle-ha07-14--claim-test--pr-109--dataset-3 http://purl.org/dc/terms/description live births at mother's ages 48 and 49;
