LACTULOSE for endometriosis
A single Open Targets database annotation lists LACTULOSE as a clinical candidate for endometriosis at an unknown clinical stage, with no mechanistic or trial detail.
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 0 of 10 overall, a exploratory reading, from a pathway rated exploratory 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. Female representation not stated — applicability to women uncertain (flagged for full text). (band F4, ×0.75).
Corroboration
Only a single database annotation from Open Targets links LACTULOSE to endometriosis, with no mechanistic detail or independent lines of evidence. No converging pathways, targets, or biological rationale are provided.
Rigor
The sole claim is a database listing of unknown clinical stage with no underlying study, model, or experimental data. There is no human, animal, or in-vitro evidence cited.
Specificity
No molecular target or mechanism of action is named for LACTULOSE in relation to endometriosis. The claim provides no information about specificity of drug action.
Plausibility
No target-phenotype relationship is described; LACTULOSE is an osmotic laxative with no stated mechanistic fit to endometriosis. The single database flag does not establish biological plausibility.
Consistency
With only one annotation and no mechanistic signals, there is nothing to assess for directional agreement. No multiple signals exist to be consistent or inconsistent.
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.

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, Pathway insights. 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.
