How teams use it

Pre-submission

Calibrate the risk register

Compare your filing's exposure against the categories that actually drive refusals, not the ones teams assume do.

Site readiness

Pressure-test the facility gate

Filter to facility and inspection deficiencies to see how often a site — not the science — held an application at the door.

Benchmarking

Track the shift over time

Follow category composition year by year, from the mid-2010s baseline through the 2024 peak in published letters.

The dashboard shows the pattern. The article explains it.

A walk through the sentences the FDA reuses across these letters, the limits of the published record, and five checks to run against a filing this quarter.
