gabapentin cream for vulvodynia
Non-RCT studies summarized in a vulvodynia review reported pre-to-posttest reductions in vulvar pain and/or dyspareunia with gabapentin cream.
Hypothesized mechanism
Topically applied gabapentin may reduce local neuropathic vulvar pain by modulating peripheral nociceptive signaling.
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 4 of 10 overall, a emerging reading, from a direct rated emerging 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
The evidence rests on a single statement summarizing non-RCT studies of gabapentin cream. No independent replication or large low-bias RCT is presented; the claim references uncontrolled pre-post observations within one review narrative.
Rigor
The claim explicitly describes 'non-RCT studies' with pre-to-posttest comparisons, i.e., uncontrolled observational designs. There is no RCT, meta-analysis, or active guideline evidence cited.
Specificity
Both the intervention (gabapentin cream) and the condition (vulvodynia, vulvar pain/dyspareunia) are named directly in the claim and source title 'Evaluation and Treatment of Vulvodynia'.
Plausibility
Topical gabapentin acting locally to reduce neuropathic vulvar pain is mechanistically plausible, but the claim provides no explicit evidenced mechanism, only observed symptom reduction.
Consistency
Only a single summary source is available, so directional consistency across independent studies cannot be assessed and is scored neutrally. The observed direction (pain reduction) is positive but uncorroborated.
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.

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, 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.
