Each dot is a biomarker; bigger dots have more companies running trials. Bottom right means many trials but few approvals: drug developers are competing to be first. Top right is crowded and established; bottom left is early or niche. Click a dot to open the page.

Counts active trials that select patients by the biomarker itself (not a broader group). Approvals are FDA-approved indications that name the biomarker. Biomarkers marked New were added in v3.0 and have had fewer accuracy checks than the others.
