conjugated equine estrogens with or without medroxyprogesterone acetate for menopause
CEE with or without MPA were the only menopausal hormonal treatments with clinical trials specifically designed to assess cardiovascular events, VTE, and breast cancer risk.
Hypothesized mechanism
Mechanism not yet characterized in the substrate.
This is the model’s proposed mechanism from the sources on file, not a demonstrated causal pathway. How well the published record supports it is reflected in the rigor and plausibility dimensions of the score, and traced to the verbatim sources at the foot of the page.
How the score was reached, for this pair
The composite score is the sum of five dimensions, each scored 0 to 2 by the model from the evidence on file. Below is the sub-score this specific pair received on each, with what that dimension measures. It scored 6 of 10 overall, a moderate reading, from a direct rated moderate in strength.
The model’s overall reasoning for this pair is the summary at the top of the page, and the mechanism it proposed is in the section above.
Scored for women. Evidence generated in women (female population). (band F1, ×1.00).
Corroboration
Evidence comes from a single review article ('Management of Menopausal Symptoms: A Review'), which constitutes one synthesis rather than independent replication. A single review scores 1 at most, and the claim is a descriptive statement about trial design rather than a corroborated outcome across multiple independent studies.
Rigor
The claim references clinical trials specifically designed to examine cardiovascular events, VTE, and breast cancer risk, and is reported in a review. Trial-based evidence summarized in a review supports a rigor score of 2.
Specificity
Both the intervention (CEE with or without MPA) and the menopausal context are named directly in the claim and quote. The drug and population are explicitly identified.
Plausibility
The claim describes only the existence of trials examining outcomes and asserts no mechanism for how CEE/MPA affects menopause or related risks. No mechanistic basis is provided in the verified claim.
Consistency
Only a single source/claim is provided, so directional agreement cannot be assessed and is not penalized. Treated as n/a, scoring 1.
Layers not covered for this pair
Not covered for this pair. This layer holds documented sex-specific pharmacokinetics for a limited set of drugs, and this compound is not among them yet. A blank here means the drug is not covered by the layer, not that no sex difference exists.
More on the sex-specific pharmacokinetics layer and its sources →Not covered for this pair. The cycle-phase layer is seeded for the strongest-evidence cases so far (PMDD), and this pair is not among them yet. A blank here means the pair is not covered by the layer, not that the effect was found to be phase-independent.
More on the cycle-phase layer and its sources →Source evidence · what the pipeline ingested
These are the sources the pipeline ingested to detect and score this signal, the published literature the model actually read, each tagged by study type. Where the model combined findings the claim is marked as a synthesis (S), and where the literature disagrees the contradiction is shown (!).
Every source below belongs to this signal’s evidence arm, Direct research. Whel reads each drug-condition pair through four such arms, each held to its own inclusion bar; a signal is surfaced through one of them.

These are the verbatim sources the pipeline surfaced and read; they may not be the full published record for a pair, and the score reflects the strength and agreement of the evidence rather than its volume. The strength of these source types is what the rigor dimension of the score reads off. MATRIX, sex-specific pharmacokinetics, and cycle phase are separate layers the pipeline does not ingest, external cross-references reported beside the score, and they link to their own sources in their sections above.
