Each dot is a condition. Horizontal position is US patient population (from CDC, NIH, and NCI SEER); vertical position is active trials divided by that population. Dot size scales with absolute trial count. Per-capita ratios are directional — trial enrollment isn't always limited to currently-prevalent patients, so read positions as relative groupings rather than precise per-capita measures.
