Filter and find all evidence in seconds
Structured trial data for every confirmed RCT. Each file contains PMID, study design metadata, SNOMED-CT intervention codes, fusion classification tier, and ClinicalTrials.gov linkage. One trial, one file, machine-ready.
A living evidence database of 58,363 ADHD abstracts, continuously enriched via EuroPMC and ClinicalTrials.gov. 19,911 papers with full text. 578 linked to registered trials.
328 doctor-validated ADHD RCTs with 93.5% classifier agreement. Each trial labeled by clinical experts with full audit trail. Covering publications from 1960 to 2026.
Every trial classified by standardized clinical intervention codes
Each abstract passes through four independent classifiers before a calibrated fusion decision
SNOMED-CT coded regex patterns across 24 intervention categories. Identifies trial design keywords including randomization, blinding, and placebo control.
Negation detection, section weighting, and implicit signal extraction. Filters out review papers and non-interventional mentions.
Sentence-transformer embeddings comparing abstracts against intervention anchor texts. Dual-score filtering with positive and negative anchors.
GOLD/SILVER/RESCUE/REJECT tier system combining Gen 2 and Gen 3 scores. Calibrated thresholds rescue unusual language patterns.
| Tier | Gen3 Score | Decision Logic |
|---|---|---|
| GOLD | > 0.4 |
Both keyword and semantic signals agree — high confidence |
| SILVER | >= 0.2 |
Design keywords detected with weak semantic support |
| RESCUE | > 0.65 |
Unusual language rescued by strong semantic similarity |
| REJECT | < 0.2 |
Neither signal found strong evidence of RCT |
