# Raw intervention lists overcount products

**Observed 2026-10-08.** Pipeworx `ct_competitive_landscape("Duchenne muscular dystrophy", active statuses)` returned 25 distinct intervention strings for a 50-trial sample. Among them:

- "delandistrogene moxeparvovec" and "ELEVIDYS" counted separately (same product, generic vs brand)
- "Sevasemten Dose 1", "Dose 2", "Dose 3" counted as three interventions
- "Brook test", "Clinical Global Impression - Severity (CGI-S)", "Descending stair walk" — outcome measures — listed as interventions
- "Placebo" was the most frequent intervention

**How to avoid:** before counting a landscape, drop placebo and assessment strings, strip dose suffixes, and merge brand/generic names through a drug resolver.
